Dear Jim:
U` � recycled paper
November 9, 1992
I am addressing two issues brought out at the on -site review of .the
Paragon Point Natural Resource Management Plan on October 22, 1992:
(1) raptor perches and (2) revegetation of the prairie dog
experimental area.
The attached letter to Walt Graul, .Regional Manager, Colorado
Division of Wildlife, requests the assistance of their raptor
biologist, Jerry Craig, to provide his recommendations for number,
type, and location of additional raptor perches by December 1,
1992.
I would like to pursue the question of revegetation of the prairie
dog experimental area with several professors at Colorado State
University over the next few months to see if they have interest in
incorporating the project into their classwork. Also, it would be
better to not disturb the experimental area now that we are into
the period of use by the large winter raptors. If taking more time
to pursue the best approach to revegetating the experimental area
presents any problems, please let me know.
Sincerely,
Karen Manci

Dear Dr. Graul:
The City of Fort Collins Natural Resources Division requests the
assistance of Jerry Craig, Colorado Division of Wildlife, raptor
biologist, to provide his recommendation for number, type, and
location of additional raptor perches at the Paragon Point
development site in accordance with the Paragon Point Natural
Resource Management Plan (Raptor Concern section attached) and for
loss of perch trees due to road construction on the eastside of the
property.
We would appreciate it if Jerry could visit the Paragon site with
Jim Sell, design consultant for the Paragon Point project, and
provide a follow-up letter with his recommendations for perch sites
to Jim Sell and to the Natural Resources Division by December 1,
1992.
Jim Sell can be reached at 484-1921.'' His address is Jim Sell
Design, 117 E. Mountain Avenue, Fort Collins, CO 80524.
Thank-you--for-your- assistance. -

RAPTOR CONCERN
This section of the plan is intended to address the use of the site by raptors or birds of prey,
specifically the ferruginous hawk and bald eagle known to use this. site to feed on prairie dogs.
Since it is not possible to retained the current prairie dog population without creating serious
problems (see prairie dog control) associated with prairie dogs in the urban environment, we
need to understand what effect reducing the prairie dog population will have on the raptors.
Unfortunately, the city's Natural Resources Department has very limited data on the prey that
raptors are relying on in the urban growth area. Bald eagles take a variety of prey including
road -killed deer, dead or dying water fowl, prairie dogs and other rodents. Ferruginoushawks
are known to feed on prairie dogs, rabbits, mice and voles.
Reducing the number of prairie dogs on the site has the effect of removing a portion of the
raptors diet. In order to encourage the raptors to continue to use this site we need to increase
other species of prey. The plan is to establish and/or maintain a variety of wildlife habitats on
the Paragon Point site. (See matrix and map.) Once prairie dog numbers are reduced and more
diverse plant associations can be established, we expect the populations of rabbits and other
small rodents to increase. Some prairie dog holes will be left available for other wildlife
species to use. In addition, a 4.6 acre area of the site has been established as.a prairie dog study
area. (See map.) The intent is to allow prairie dogs to exist in this limited area to the degree
that they can exist without threatening the vegetative cover.
Other measures designed to encourage the use of the site by raptors include providing open
water that will attract water fowl and providing perch sites for the raptors to use. (See perch
site diagram below.)
It must be recognized that elements of this plan designed to encourage the raptors to stay are
experimental. .It may not be possible to retain the raptors on this site, given that other areas
within and outside the urban growth area provide habitats that included larger populations of
prairie dogs (easy prey) further removed from human disturbances. The experiment, however,
provides an opportunity for the city to learn whether or not urban development and raptors can
.co -exist.
