EcoPlan’s in-house biologists frequently prepare biological evaluations and assessments, preliminary site screening reports, biological monitoring plans and summary reports, and terrestrial and aquatic species and habitat conservation plans.


Our research assignments include but are not limited to the following:

  • Special status species surveys

  • Soil Hydrology Studies

  • Ecological Studies

  • Revegetation and Reclamation

  • Plant and Wildlife Inventories

  • Riparian Community Surveys

2018 Fort Thomas Avian Surveys

In January 2019, on behalf of SRP, Ecoplan completed their 6th year of avian surveys on the Fort Thomas preserve. EcoPlan surveyed southwestern willow flycatcher (SWFL) and yellow-billed cuckoo (YBCU) populations within the two study areas, totaling 1,253 acres. As part of this study, habitat conditions were recorded, and photos were taken to meet the obligations of the two habitat conservation plans. During the 2018 surveys, a record number of SWFL (pictured top right) territories were recorded.

These surveys are required as part of mitigation obligations under the Roosevelt Lake Habitat Conservation Plan and the Horseshoe-Bartlett Habitat Conservation Plan, SRP and the U.S. Bureau of Reclamation (USBR) acquired riparian habitat along the Gila River in Graham County, Arizona. SRP is required to monitor the effectiveness of mitigation measures by conducting periodic surveys of WIFL and YBCU populations and evaluating habitat condition at the mitigation properties.


Southwestern Willow Flycatcher

Experts can distinguish the Willow Flycatchers from other look-alike species by their loud, raspy "fitz-bew" song.


Arizona Cliff-Rose

The Arizona Cliff-Rose has been listed as endangered since 1984.


Desert Tortoise

The Desert Tortoise is native to California, Arizona, Nevada and Utah and have a life span of up to 50 years.
