Fellow Ithacans,
On November 8, 2010, the trustees of Cayuga Heights released a draft environmental impact
statement (DEIS) in support of their "Deer Management Plan."Their proposal entails identifying a
small number of deer in the village who will be allowed to live, each of whom will be captured,
surgically sterilized, and fitted with ear tags and radio-collars. These marked survivors will be the only
deer spared when an annual program slaughters all other deer in the village, utilizing either "bait and
shoot' or "net and bolt" to be carried out in residential neighborhoods.
This document offers 19 statements critical of the deer-killing plan and of the DEIS that supports it, all
of which were submitted to the trustees within the State-required comment period, which ended on
December 16th. These statements were written by residents from Cayuga Heights as well as from
other Ithaca-area municipalities, sometimes from their perspective as concerned citizens, and in
many cases, expressing their opinions as trained professionals in one or more relevant areas of
expertise.
In addition to the 14 citizen statements offered within, there are also statements from four scientific
experts who were approached by brLa Dfuyan,,a 3g4wa resident of our,comrrWnjtY and noted
author and science educator, who asked each to evaluate and comment upon parts of the DEIS that
fell within the realm of their professional expertise. Additionally, the executive director of a national
nonprofit organization involved in food and water quality issues contributed her evaluation. None of
these experts were paid or compensated in any way for the time they generously devoted to this task.
None of these individuals have had previous involvement in the controversy over this plan.And as is
also true of all the included citizen statements, their opinions stand on their own, and the inclusion of
their statements in this document does not imply an endorsement of any particular individual,
organization or point of view.
Home addresses and signatures have been redacted. Header information identifying the statement
authors' last names and page numbers have been added. Otherwise the content of all statements
appear in the document as they were submitted to the Village of Cayuga Heights.

Re: Draft Deer Management Environmental Impact Statement
Dear Trustees:
I am a scientist with 20 years' experience dealing with urban deer issues and carrying out
research into non-lethal methods of suburban deer population control. I have several concerns
and comments regarding the information that the Trustees are using to make decisions about a
deer management plan for the Village.
In building a case for taking action, the DEIS makes clear that it is the impacts of the deer, rather
than their numbers, that should shape management actions. However, the objectives of the
proposed management effort are expressed only in terms of deer numbers. No targets are set for
reductions in deer-vehicle collisions, reductions in impacts on ornamental plantings, reduction in
Lyme disease rates, or restoration of biodiversity. Indeed, because the Village appears to have
no information at all on deer impacts on ornamental plantings or on biodiversity that are specific
to the Village itself(or even plant inventories within the Village's small natural areas), such
targets are currently impossible to set. Likewise, although the DEIS waves the Lyme disease
flag, it presents no site-specific data related to Lyme disease incidence or risk, and consequently
concedes any prospect for measuring reduction in disease risk associated with the proposed deer
management action.
In my view, accurate deer population numbers are important for the development of management
plans mostly because they define the scope of deer population management. Because there has
been no population assessment for four years, there remains much uncertainty about the number
of deer present, and hence about the outcome of any deer reduction effort. Extrapolation of
wildlife population growth rates into the future is purely speculative, and the further into the
future one extrapolates, the more speculative it is. In Cayuga Heights, where deer population
estimates apparently were stable between 2002 and 2006, there is certainly no sound basis to
postulate a 10% increase over the four years that followed.

Allen Rutberg, PhD(p. 1-2)-Page 2
From a population management perspective, the DEIS commits a serious oversight in completely
omitting any reference to less invasive methods of controlling fertility in deer. There are two
injectable immunocontraceptive vaccines that have been shown to be effective in deer: the
I and my collaborators have been working on for
porcine zona pellucida (PZP) vaccine, which
more than 20 years, and GonaCon Is, an EPA-registered vaccine that was developed by the
USDA's National Wildlife Research Center. Safety, effectiveness, and population impacts in
suburban deer have been extensively documented for PZP in particular, and recent technological
advances have eliminated the need for annual retreatments (see especially Turner et al.,
"Controlled-release components of PZP contraceptive vaccine extend duration of infertility
Wildlife Research 35:555-562 (2008); Rutberg and Naugle, "Population-level effects of
immunocontraception in white-tailed deer," Wildlife Research 35:494-501 (2008): and Rutberg
and Naugle, "Deer-vehicle collision trends at a suburban immunocontraception site," Human-
Wildlifi Conflicts 2:60-67 (2008)). There may ultimately be reasons for not choosing to employ
either of these vaccines, but both deserve serious consideration in a legitimate EIS.
Finally, as a trained ecologist who values wildlife as wildlife, I find myself extremely disturbed
by the proposal to capture and sterilize a subpopulation of wild deer and exterminate the rest.
With this management model, the Village of Cayuga Heights aspires to reduce its wild deer
population to a state of semi-domestication. I do not see much of a future for the coexistence of
people and wildlife if even as progressive a community as Cayuga Heights cannot tolerate
wildlife within its boundaries.
I strongly recommend that the Trustees take a harder look at the proposed management plan,
better define their objectives to meet the community's legitimate concerns with deer, and further
consider less invasive means for managing the Village's conflict with deer.

Dear Trustees,
1 am,herewith, commenting on the plan to control white-tailed deer within the town limits of the Village of Cayuga
Heights. In providing this comment, I wish to affirm that I am not being paid by anyone for this service. 1 am providing
feedback in my capacity as an ecologist who has studied white-tailed deer for my PhD dissertation and subsequent
research. I have published 6 peer-reviewed papers and book chapters dealing with white-tailed deer ecology and
population management.
I have looked at all of the documents provided at the website for the draft environmental impact statement (DEIS)
hap:. %N�c��.tiinnuilrrusocimes.conrpublierccic%t cavupllckjut . I am working under the understanding that this is the
official document for which comment is request. Below I identify specific informational content in the documents and
offer subsequent comment.
In the document 2.0 DESCRIPTION OF THE PROPOSED ACTION the proposed deer population control effort in the
Village of Cayuga Heights(VCH) is based on the following premises. (1) Many studies in the past 20-25 years suggest
that high deer densities affect plant species composition,biodiversity and forest regeneration(pages 2-2,2-3). (2)A
substantial deer density can significantly influence wildlife habitat and deer foraging can compromise the ability of an
ecosystem to recover, leading to alteration of forest composition and structure(page 2-3). (3) Deer populations above 10
deer per square mile are undesirable if the management goal is to achieve maximum biodiversity(page 2-3). (4)To
minimize losses of animal and plant diversity, the management target should be 30 deer or fewer within VCH,or a
density of 15 deer per square mile or fewer(Page 2-4).
Conancnr
Re: (1)The document is correct in stating that research over the past 20-25 years has examined how deer can affect
species composition, biodiversity and forest regeneration. However, many of these studies are in a single location and
could thus be conflated by human land use type and land-use history so that deer cannot be concluded to be a leading
factor determining the impact in any one of these studies(see Rutherford and Schmitz 2010,Journal of Wildlife
Management 76:1257-126 3). Indeed, such conflation of land use on deer populations has been alluded to in 2.3 Project
Background... which claims that agricultural practices and forest management has improved and expanded deer habitat
and suburbanization of landscapes has created edge habitats preferred by deer(page 2-2).
Re: (2) It is correct that high deer densities can significantly influence habitat and forest composition and structure.
However,our research(Rutherford and Schmitz 2010), conducted in a similar landscape as VCH, and includes several
replicated town sites,again shows that these damage levels are unrelated to deer density per se across a wide range of
deer densities. This means that lowering deer densities will not by itself lessen deer impacts on habitat and vegetation.
Furthermore, the DEIS never provides criteria for quantifying and assessing damage levels that are acceptable or
unacceptable. Hence, there are no a priori criteria to judge success of management aimed at lessening"damage".
Re: (3 &4)The document is correct that deer densities above 10-15 per square mile can be quite damaging in some areas.
But, again, there is wide variation in damage levels, meaning that t0-15 is not a damage threshold,as implied by the
document.
Cayuga Heights Deer Management Plan DEIS:Independent Expert Response
Oswald Shmitz,PhD(p. 3-4)-Page 4
The document identifies several management goals including(5) VCH should adopt a cultural carrying capacity goal of
15 doer per square mile(page 2-7). (6)VCH should begin a Phased Options Approach(POA)beginning with sterilization
of 20-60 does and subsequent culling of unsterilized does(Page 2-7). (7) POA must be implemented in each of the first 5
years of the management program(Page 2-8)and may require continuous implementation in perpetuity(Page 2-9).
Comment
Re: (5) 1 see no evidence that this population size goal is attainable for 2 reasons. First, the document itself states that
deer population (sizes] are difficult to ascertain accurately due to daily and seasonal movements(page 2-4). Thus,there
is no evidence provided that accurate estimates of deer will be obtainable to judge the success of the management.
Second,because of the acknowledged daily and seasonal movements,the deer population in VCH may not be closed—
meaning deer may not be confined within the town boundaries,but may enter and leave VCH. There is further evidence
to suggest that VCH does not have a closed population. The current reported deer population sizes(Letter to VCH
Trustees from Paul Curtis Dated 12/9/2009--Appendix A) indicates that the deer population size(presumably within
VCH boundaries —the exact area of the population estimate is not specified) is very high by deer population standards.
However, the population was only sampled in the spring(according to the letter) so the seasonal movement of deer
remains unclear. One might expect that under such high abundances,that deer birth rates would slow because of
competition for food (called density-dependent feedback). The claim that the deer population is still growing
prodigiously(according to the letter)means there is incomplete understanding about the population dynamics on this
landscape. One possibility is that deer are moving seasonally into and out of the VCH from the surrounding landscape,
are highly abundant seasonally,but are not resident within the VCH. The fact that this alternative cannot be ruled out has
implications for(6)and(7).
Re: (6)Sterilization, if it works at all,will only work for a closed population. The fact that the DEIS has not provided
evidence that the VCH deer population is a closed population means that sterilization, and hence a PDA as defined in the
document could be altogether untenable. Furthermore, if the population is open,then it will be difficult to reach a target
"stable"population size of 15 deer per square mile,even within a single culling period. Because culled deer could be
rapidly replaced by deer from the landscape surrounding VCH,there is a likelihood that even a 5 year time horizon will
be insufficient to reach a target population size. it may never be reached with an open population and culling efforts
focused only on a small part of the greater landscape.
Re: (7)The document is correct in suspecting that the POA will need to be implemented in perpetuity, especially if the
VCH deer population is not a closed population.
In summary,there is insufficient evidence provided in the documentation to show that the management effort will achieve
its stated objective deer population size of 15 per square mile within VCI1. Evidence to support the assertion that a deer
population size reduction will lessen impacts on ecosystems(habitat and vegetation)within VCH is also insufficient.
Furthermore,the DEIS needs to consider the conflating effects of human land use as a driver of deer movements and
population growth on this landscape. That is, deer populations may be the consequence of human impacts on the
landscape rather than a cause of impacts to humans.

Subject: Draft Environmental Impact Statement, Cayuga Heights Deer Management
Plan
I am a research scientist who has devoted much of the past twenty years to
understanding the ecology of Lyme disease and other tick-borne infections(set!
). I have carefully read all sections
of your DEIS pertaining to the potential impacts of management options on ticks and
tick-ix)me disease. The DEIS contains many inaccurate and unsupported statements
about relationships between deer, blacklegged ticks (incorrectly called "deer ticks"),
and Lyme disease for example, page 2-10 incorrectly states that linear correlations
exist between deer and ticks. A comprehensive review of the scientific literature on the
relationship between numbers of deer and numbers ut ticks reveals that the majority of
studies find no statistical correlation at all (see- Ostfeld, R-S. 2011. Lyme disease: the
ecology of a complex system. Oxford University Press, New York.). The lack of a
correlation derives from the following facts: (1) deer do not infect ticks with Lyme
bacteria, and actually reduce the infection prevalence in tick populations; (2) adult
blacklegged ticks feed on at least 27 different species of mammals and are not specialists
on white-tailed deer; (3) when deer populations are culled, ticks crowd onto the
remaining deer, resulting in similar total numbers of tick meals; and (4)even when deer
affect the number of eggs laid by adult ticks and resulting abundance of larvae.
numbers of larvae do not predict numbers of nymphs(nymphs are resl%onsible for
transmitting Lyme disease to people).
On page 3-5 the document cites the Monhegan Island fMafne) study to protect what
might happen in Cayuga Heights. This is misleading. On Monhegan Island, the deer
herd was hunted from 100 to zuro individuals. No other host animals for the adult
stage of the tick were present on the island. 'Therefore, with no other host on which to
Cayuga Heights Deer Management Plan DENS:Independent Expert Response
Richard Ostfeld,PhD(p.5-6)Page-6
complete their life cycle, the blacklegged ticks declined dramatically. But when deer
have bmn culled on mainland sites, management never achieves extirpation of deer,
and the remaining deer plus many other hosts suplwrt adult ticks. Iherefore, control of
ticks is weak to nonexistent. Moreover, although mention is made of deer thresholds in
the non-peer-reviewed literature, no scientific data support the existence of a deer
density threshold below which ticks decline to low numbers. Scientific literature on
which my statements are based can be found in the book cited above.
I refrain from commenting on other arguments concerning the benefits of culling deer.
However, to the extent that the justification is based on the notion that reduced Lyme
disease incidence will result,the document is deeply flawed.
I would be happy to address questions should any arise.

Subject: Draft Environmental Impact Statement — Cayuga
Heights Deer Management Plan
Dear Board of Trustees,
I am a scientist and teacher at the Harvard School of Public Health in
the Department of Global Health and Population.
http://www hsph harvard edu/research/tamaraawerbuchfriedlander/in
dex.html.
One of my main contributions to science is my research on the
ecology of the vector that transmits the Lyme disease bacteria, which
appeared in peer reviewed publications in scientific journals.
The essence of my findings is also described in the home page of my
school:
http //www hsph harvard edu/news/features/features/kiling-deer-not-
answer-red ucing-Iyme-disease.html.
After reading your DEIS pertaining to potential outcomes of
management programs to reduce tick populations by killing deer, I
was surprised at the lack of a scientific basis, moreover at the
incorrect assumptions about the relationship between deer and the so
called "deer tick"; the scientific name of blacklegged ticks is Ixodes
dammini, the name given by Dr. Andrew Spielman, a colleague in our
school, who discovered that this is the vector of the disease.
The life cycle of the tick is quite complex, it is only The adult tick that
takes a blood meal from deer, lays eggs and then dies. Deer do not
carry the agent of Lyme disease; the white-footed mice do.
In Crane Beach [in Ipswich, MA], where I conducted my study,
people thought that if they killed deer they would reduce the number
of ticks, and thereby control Lyme disease. Deer were reduced [from
around 400 in 1983 to just over 100 in 1991], but Lyme disease kept

Tamara Awerhuch, PhD(p.7-9)Page-8
growing. The question was why? We killed deer but people still got
Lyme disease.
So I did a study using a mathematical model to capture the life cycle
of the tick. Because the ecology of Lyme disease is so complex, it is
very hard to look at deer and tick, mouse and tick, one by one. You
have to link all the factors together in a way that lends itself to
mathematical analysis.
The following figure shows the reduction in deer number throughout
the years, and the line shows the increase in larvae ticks in Ipswich,
Mass.

The larvae pick up the infection from infected mice, and those that do
not die, molt into infected nymphs which are the ones that transmit
the infection.
Cayuga Heights Deer Management Plan DEIS:Independent Expert Response Tamara Awerbuch. PhD(p.7-9)Page-9
So there is NO LINEAR correlation between killing deer and the tick
population.
On Monhegan Island it was possible to get totally rid of the tick
population because ALL deer were killed and no other animals were
there to take over the empty niche left by the deer to support the adult
tick.
So in summary, there is NO scientific justification for a deer killing
program in your community of Cayuga Heights, NY. There are
certainly alternative ways for reducing the risk of Lyme disease.
As we saw using data from Ipswich Mass. where there was an

Dear Madam or Sir:
The Village of Cayuga Heights has recently proposed an aggressive deer population control
program in response to an increased deer population. The proposal is justified in part by the
purported public health risk from runoff tainted with deer waste.[
I am the executive director of Food & Water Watch, a national consumer organization that
studies both municipal water systems and the impact of large livestock operations on the
environment. Food & Water Watch has written extensively on the damage that excessive animal
waste can have on local watersheds and the concomitant impact on clean municipal drinking
water.
Certainly animal waste can pose risks to drinking water supplies, but the slight risks posed by
waste from wild deer can be easily mitigated by less aggressive, less risky and less expensive
approaches than the net-and-bolt strategy currently favored by the Deer Remediation Advisory
Committee.
First, the focus on deer as the key source of microbiological contamination risk may be
misplaced. It is far from clear that deer are the primary source of any runoff contamination.
Some localities have found that waterfowl were the primary source of wildlife waste runoff.'
Using U.S. Department of Agriculture data, Food & Water Watch recently reported that
Tompkins County contains nearly 3,600 dairy cows on the largest class of farms that produce
145 million pounds of untreated manure every year.
Determining the existence and source of any manure or wildlife waste runoff must be the first
step in developing an appropriate policy to mitigate the risk of water contamination. The U.S.
Environmental Protection Agency recommends tracking the bacterial source of non-point
microbiological contamination before putting a plan in place. Inexpensive alternatives to assess
the source of any runoff pollution include antibiotic resistance analysis that can pinpoint the risk
from deer.` Until native deer are determined to be the source of any waterborne bacteriological

contamination, it would be ill advised to pursue an expensive and dangerous program to limit the
deer population.
If wild native deer are determined to be the source of any runoff contamination, there are many
less expensive, less dangerous and more effective policies that can provide greater protection to
municipal water sources. The most effective strategies to reducing contamination from runoff are
to improve the grade, contour, buffer and foliage surrounding waterways to provide natural
filtration and reduce the speed of water runoff.
The New England Interstate Water Pollution Control Commission recommends habitat
modification (including landscape changes and tree branch pruning), preventing human feeding
of wildlife (especially waterfowl), monitoring wildlife populations in and around water supplies,
deterring wildlife from vulnerable watershed areas and reducing available food sources." These
strategies have the added advantage of addressing the extant deer population but also any future
deer that may enter the community and repopulate the area after any short-term deer population
control strategies.
There are a host of additional legitimate criticisms to the proposed strategy to control the native
deer population. The proposal includes a waiver from New York state rules to use "net-and-bolt"
methods that are usually banned because they are inhumane.7 It would be expensive, intrusive
and potentially dangerous to local citizens and pets to deploy explosive nets within the village
residential areas. Short-term population control mechanisms over native deer only address the
current deer, not the long-term existence of whitetail deer in Western New York. Although the
current deer might be controlled, more deer will likely come to the village.
It is especially disingenuous to use the legitimate concern of water contamination to justify a
policy that is considerably more draconian than necessary to protect the village water supply.
There are a host of more affordable, more effective, and less dangerous and aggressive policies
to protect the village's water supply than the proposed net-and-bolt so-called strategy offered by
the Deer Remediation Advisory Committee. Stopping the spread of dangerous pathogens and
chemicals in Our water is a legitimate concern for all governments. But using those concerns as a
scare tactic neither serves the people of Cayuga Heights nor protects the water resources of the
area.

RE: Draft Environmental Impact Statement Regarding Deer Population Control
We are five members of the faculty of Cornell Law School and all residents of
Ithaca, two of us living in Cayuga Heights. We write in our individual capacities as
citizens, informed by our knowledge of the law. We wish to express dismay with the
draft environmental impact statement ("DEIS") regarding the current plan to slaughter
most of the deer in Cayuga Heights.
New York law requires that an environmental impact statement"must analyze the
significant adverse impacts and evaluate all reasonable alternatives" [6 NYCRR
617.9(b)(1)]. For four chief reasons, we believe that the DEIS fails this basic
requirement.
1. The DEIS parades assertions but does not provide adequate support on
such vital matters as the determination of the current deer population of Cayuga Heights
based on a reliable field study, the acquisition of community-specific biodiversity data,
the analysis of the likelihood that deer will migrate into Cayuga Heights from
surrounding areas, or the likely impact of contraception with vaccine or surgical
sterilization, relaxing the fencing ordinance, or the combination of these and other non-
lethal alternative methods of reducing the level of deer-human impact. The EIS thus lists
alternatives, but in violation of state law, it fails seriously to consider those alternatives.
Further, the very choice to define the goal of the action itself as being to reduce the deer
population, rather than to reduce the impact of deer-human conflict, appears to be a
device used to avoid responsibility for taking a "hard look" at the numerous non-lethal
alternatives, some of which, such as a more flexible fencing ordinance, are being
successfully used in neighboring municipalities.
In the Environmental Assessment Form (Appendix A of the DEIS), the
examination of viable alternatives with demonstrably lower negative impacts is
repeatedly circumvented by the circular declaration that "any modification of the plan
would result in not lowering the deer population, which is the goal of the action." With
due respect, the issue at hand is not a widespread objection amongst the citizenry to the
very existence of the deer, but to the impact caused by conflicts with the deer. By
reducing the alleged problem to "too many deer," the DEIS opens the door to
sidestepping the need to analyze and quantify the various dimensions of deer-human
conflict and of proposed solutions. Doing so would lead to a more realistic
understanding of the issue, a more meaningful evaluation of alternatives, and a more
effective evaluation of the success or failure of the program, all of which would serve the
underlying purposes of our state's environmental laws and the best interests of the
community.

2. The DEIS nowhere considers the impact on the deer themselves. It calls
the "net and bolt" method of slaughter a form of"euthanasia," a particularly odd term to
describe the killing of healthy animals. As for the method itself, even those who practice
it admit that it causes great suffering and therefore cannot plausibly be termed "humane."
The DEIS does not consider the evidence that captive bolts fired at netted deer frequently
miss their target, causing prolonged deaths. Moreover, the plan is inherently cruel, both
to those animals targeted for unnecessary slaughter and to those marked for survival who
will be forced to watch their herd-mates systematically massacred in front of them,
whether the killing is carried out with firearms or captive-bolt devices. Exacerbating this
cruelty is the fact that it will be repeated, year after year, and will thus subject large
numbers of gentle living beings to terrible physical pain, emotional agony, and death.
3. Numerous people in our community have publicly expressed the pain and
anxiety that they feel at the prospect of individual deer whom they have come to know
being violently killed. Some of the people likely to be traumatized by the violent plan
will be children. Others may be those with pre-existing mental health conditions
connected to previous exposure to violence that could be exacerbated through inadvertent
witnessing the sights or sounds of the killing process or even by knowledge of being in
close proximity to locations where mass killing is being carried out. The DEIS callously
dismisses such actual traumatization as mere "community controversy," which, it states
"is not a criteria [sic] for determining significance." Yet the emotional wellbeing of
community residents is an aspect of"human health" that must be specifically and
objectively assessed in the DEIS. "Human health" is expressly included in SEQRA's
definition of"environment." [See 6 NYCRR 6I7.2(1).] Additionally, "the creation of a
hazard to human health" is listed in the SEQR regulations as an "indicator of significant
adverse impacts on the environment." [See 6 NYCRR 617/7(c)(1)(vii).]
4. Discharging deadly weapons in close proximity to homes and roadways—
as the deer-killing plan entails—poses danger to the people of our community. It is
impossible to eliminate this danger completely, and it will affect more people than those
who reside in the village, including those who live in neighboring municipalities as well
as those who drive through the village's many roadways. The precise location of the
killing will apparently remain undisclosed; the DEIS lists it as the entire Village of
Cayuga Heights. Thus, people in the vicinity will be unable to protect themselves and
their loved ones—both human and nonhuman—from potential harm. A bullet meant for an
innocent deer can foreseeably wound and kill an innocent human, dog, cat, or other
fellow inhabitant of this generally peaceful village, town, and city.
Hence, we encourage the trustees to step back and reassess the likely Iona term
effects of the proposed deer-slaughter plan on both Cayuga Heights and the larger Ithaca
community. The trustees have a final opportunity now to bring us all together with a
creative, non-violent solution, and we hope they take it.
Should the trustees proceed with implementing the currently proposed plan, we

will continue to express our opposition and encourage others to do the same. Should a
legal challenge become necessary, we will lend our support to it. The current deer-
slaughter plan would damage our community for many years to come. There is still time
to reconsider, and in doing so, preserve the good will and sense of unity our community
will doubtless need in the challenging times ahead.
