Does the institution own or manage land that includes or is adjacent to legally protected areas, internationally recognized areas, priority sites for biodiversity, or regions of conservation importance?:

A brief description of the legally protected areas, internationally recognized areas, priority sites for biodiversity, and/or regions of conservation importance:

Whitman owns land in northeastern Washington State that is enrolled in the Conservation Reserve Program (CRP), which is administered through the Natural Resources Conservation Service (NRCS). A total of about 1,900 acres are enrolled in the program.

Whitman owns and operates 1,800 acres of land as part of its Wallula Gap Biological Station, where research on native grassland ecology, conservation, and carbon sequestration is conducted.

Has the institution conducted an assessment to identify endangered and vulnerable species (including migratory species) with habitats on land owned or managed by the institution?:

A list of endangered and vulnerable species with habitats on land owned or managed by the institution, by level of extinction risk:

Wallula Gap Biological Station:

Wallula Gap Biological Station:
· Ferruginous hawk (Buteo regalis) - concern - one pair breeds at the site.
· Golden eagle (Aquila chrysaetos) - concern - rare winter visitor, occurrence frequency unknown
· Loggerhead shrike (Lanius ludovicianus) - concern - rare breeder, present every summer
· Sage thrasher (Oreoscoptes montanus) - concern - rare migrant, occurrence frequency unknown
· Western toad ( Priority Species under WDFW's Priority Habitat and Species Program)- detected for the first time in summer 2022 at Wallula Gap Biological Station. Multiple adults in vernal pool
- Palouse prairie plant community: this is a native grassland that has been mostly destroyed by agricultural and residential development. With less than 1% of the original habitat remaining, our native Palouse Prairie is the most endangered ecosystem in the continental United States.
- Eastside Steppe (Terrestrial Priority Habitat)
- Juniper savannah (Terrestrial Priority Habitat)
- Shrubsteppe (Terrestrial Priority Habitat)

Johnston Wilderness Campus in the foothills of the Blue Mountains:

·The long-toed salamander (Ambystoma macrodactylum) - concern

Has the institution conducted an assessment to identify areas of biodiversity importance on land owned or managed by the institution?:

A brief description of areas of biodiversity importance on land owned or managed by the institution:

1) Wallula Gap Biological Station, with vestiges of native Palouse Prairie habitat

2) College Cabin property and Johnston Wilderness Campus, both in the foothills of the Blue Mountains, with native forest habitat

3) Water-Wise Garden, a garden (initially designed by students in 2007) on the campus, with native low-water plant species and now also supporting a diversity of native insects, including bees.

The methodologies used to identify endangered and vulnerable species and/or areas of biodiversity importance and any ongoing assessment and monitoring mechanisms:

1) Wallula Gap Biological Station: Prof. Tim Parker keeps current records of observed birds

2) College Cabin: Prof. Emeritus Chuck Drabek (Biology) supervised a survey of small mammals by a student (Shari Rodriguez) in 1993, with various collections and observations made over the years prior to that. Johnston Wilderness Campus: A full-year survey (documentation through herbarium specimens) of the plants was conducted in 2002-03 by a student (Andrea Freng) under the guidance of Heidi Dobson. On Spring semester field trips for the introductory biology course, Prof. Kate Jackson (Biology) has found both eggs and adults of the long-toed salamander (Ambystoma macrodactylum) in the pond; this salamander species currently has a IUCN listing of Least Concern, but there is a paucity of information on its distribution in the general region of the Blue Mountains.

3) Water-Wise Garden: Prof. Heidi Dobson (Biology) and her students have surveyed the native bee species visiting flowers in the Water-Wise Garden over the summers 2021 and 2022.

4) Whitman Campus flower beds: We conducted one full summer survey of flower-visiting insects (2022) and collected two specimens of one vulnerable bumble bee species, Bombus occidentalis.

A brief description of the scope of the assessment(s):

All college-owned property was considered.

A brief description of the plans or programs in place to protect or positively affect identified species, habitats, and/or ecosystems:

1) Wallula Gap Biological Station: the college (through Tim Parker) has entered into an agreement with the Washington State Dept. of Fish and Wildlife to construct two artificial nesting platforms for the Ferruginous hawk, which accepts platforms for nesting. Two platforms were constructed in Fall 2019: one at the biological station and another at a different Whitman property near Starbuck. The newly constructed platform at Wallula Gap has been used to nest by Ferruginous hawks each spring since 2020 (including 2023).

2) Johnston Wilderness Campus: the Whitman College Trees and Landscaping Committee has requested that the pond and its surroundings not be disturbed during maintenance activities.

3) Water-Wise Garden: Heidi Dobson and the College Grounds have worked together to provide habitat for the low-growing perennials, which are visited by a diversity of insects. In fall 2018, large shade-producing plants were pruned and invasive native grasses removed, and new plants were established to maintain a diversity of plant species for insects. No pesticides are applied to the area, and bee populations are disturbed minimally for research.
