Avimor Stewardship Organization, Inc.

The Avimor development is deeply committed to the restoration and revegetation of key habitats for birds, insects, and wildlife. We are passionate about preserving the ecosystem of the foothills, and our development reflects our effort to live in harmony with nature. That is why we created the Avimor Stewardship Organization. It sponsors programs and activities to preserve and protect the environmentally sensitive areas in Avimor. It also creates a sense of "Community" by sponsoring programs and fun activities that get the residents involved in the community and with each other.

Avimor Homeowner's Guide to Living with Wildlife

Living at Avimor will offer you an amazing opportunity to experience native plant communities and wildlife right in your own backyard. However, those living in this beautiful location are also responsible for protecting its integrity and wildlife value.  We must educate others on the ecology of the area and engage in good stewardship practices, which is why every homeowner in Avimor receives a copy of the Avimor Homeowner's Guide to Living with Wildlife. This handbook emphasizes the fact that the decisions we make with respect to our own backyards will affect the neighboring wildlife and associated habitat. Good stewardship practices such as planting native vegetation for landscaping, restricting the use of foothills trails during winter months, using organic fertilizers, and maintaining bird feeders will not only reduce impacts on wildlife but will also bring you many hours of enjoyment.

Avimor Conservation Easement

Avimor and the Ada Soil & Water Conservation District have designated approximately 400 acres of Avimor property as a permanent conservation easement. This property is valuable for its natural wildlife, recreational, and scenic value, and it will remain undeveloped in perpetuity.  View Avimor Conservation Easement: Click Here

Noxious Weeds

They are the uninvited guests who never leave...noxious weeds.  View Avimor Guide to Living with Wildlife: Click Here

Native Plants

Using native plant species for your landscaping needs is ideal. Native plants are already adapted to the foothill's climate and soil type, and they exist in balance with other plants and animals.  As a result, native plants will generally require less water and maintenance and will be more resistant to insects and diseases than exotic plants. Native plants can also eliminate the need for herbicides and chemical fertilizers, which helps protect the soil and water from contamination. View List of Native Boise Foothills Plants. The Garden for Wildlife website from the National Wildlife Federation is a great resource for anyone interested in learning more about creating wildlife habitat in their own yard.

Butterfly Gardens

Many butterfly species and other pollinating insects are selective of the flowers they feed on. For example, Monarch caterpillars exclusively require milkweed plants. Swallowtails are attracted to parsnip, parsley, dill, fennel, and celery. A large number of butterflies are also attracted to blanket flowers, mallows, trilliums, clarkia, and wild strawberries. In general, ornate-aromatic species with colorful flowers will be used by many native pollinators.

Avimor Birding

More than 150 bird species have been documented at Avimor. This list of all bird species seen in the area is being compiled by residents, employees, contractors, and visitors of Avimor. We are confident that as riparian and shrub steppe areas are restored with native vegetation, populations of native birds will return and thrive. We can use your help in tracking our progress, and we request that you let us know of any special sightings of birds.

Firewise is a national program that involves homeowners, community leaders, planners, developers, and others in the effort to protect people, property, and natural resources from the risk of wildland fire -  before a fire starts. Learn more

Best Birding Locations at Avimor

  • Spring Valley Creek Greenbelt
    • Running parallel to Highway 55 is Spring Valley Creek. Along the east bank is a paved trail which provides easy access to great elevated views over the trees and shrubs along the creek. Perfect for viewing and photographing birds.

  • Heritage Park
    • Heritage Park is surrounded by riparian area on all sides. Paved walkways here make for easy access as you make your way around the park enjoying the variety of plant life playing host to the diversity of bird life.

  • Twisted Spring Trailhead Pond
    • In spring, this shallow pond is a favorite of ducks and shorebirds. The cottonwood stand north of the pond regularly hosts nesting Red-tailed Hawks. The bushes around the pond are great places to find a huge variety of songbirds.

  • Twisted Spring & Spring Valley Creek Trails
    • One of Avimor's most scenic and enjoyable hikes. There is great birding along the whole trail. Once you get into the steep rocky areas be on the lookout for Canyon and Rock Wrens, maybe even Chukar.

  • Avimor Town Lake
    • The pond attracts ducks, geese, herons, kingfishers, swallows, and nighthawks. The trees around the ponds are often decorated with several kinds of birds.

  • Pearl Road Drive
    • The drive along Pearl Road from the top of Horseshoe Bend summit all the way to the historic site of the mining town of Pearl, then to Willow Creek Rd is both scenic and birdy. Look for Sage Thrashers and Eastern Kingbirds in Spring and Summer.

  • Chinese Well Riparian Area
    • On the west side of Hwy 55, across from the construction trailer, is a private access area, but has been a great location for rare birds including a Rusty Blackbird, nesting Long-eared Owls, and a regular spot for Gray Partridge. The lower portion is marshy and the upper section is craggy with hackberry trees. See Robert at the Avimor office for a guided tour of this area.

  • Historic Toll Gate Ranch
    • Intrepid hikers or mountain bikers can make it into the Avimor backcountry. Several creeks and trails all intersect at the historic Toll Gate Ranch on old Cartwright Road. The area is pretty lush for desert hills and attracts all kinds of wildlife.

Firewise Community

Firewise Status:

Avimor has been designated as a Firewise community in accordance with the national Firewise Communities program. This program is a multi-agency effort designed to reach beyond the local fire service provided by the Eagle Fire Department and the Bureau of Land Management. To date, Avimor has mowed and applied herbicide on approximately 92 acres of natural open space to reduce the amount and continuity of fuels within, and adjacent to, the community. Proactive work such as this will continue to grow on a yearly basis. Avimor has also held a series of meetings with both the Eagle Fire Department and the Bureau of Land Management to develop effective strategies to prevent wildfires around the community.

Avimor Fire Plan

As part of the Firewise development requirements, Avimor developed a Fire and Vegetation Management Plan. This plan provides guidelines for how the Avimor homeowners, the HOA, and the Avimor Conservation Director can reduce the potential risk of wildfire and improve the health and stability of the surrounding vegetation and wildlife.
