Human impacts on trust species of the U. S. Fish and Wildlife Service
(USFWS) can take many forms, including incidental take (e.g., albatross
mortality on fishing long lines, manatee mortality due to loss of warm-water
habitat) and harassment (e.g., jogging in the vicinity of feeding waterbirds).
The management of diverse biological taxa can involve common themes
in terms of managing human activities and modeling the impact thereof,
and designing programs to monitor those impacts. The primary objectives
of this study are to model diverse human-induced impacts as well as
provide study designs to better collect data to model such impacts.
Estimation methods and study designs will be developed and applied to
trust species of the USFWS.
1) Evaluate albatross banding data from the Northwest Hawaiian Islands
and design future banding studies to estimate the effects of fishing
on survival and breeding probability of albatross populations.
2) Develop predictive, spatially structured models to simulate Florida
manatee behavior and population dynamics, particularly regarding manatee
use of warm-water sites during winter.
3) Design a study of the impact of joggers and other recreational users
on waterbird use and behavior at National Wildlife Refuges of the northeastern
Progress: Albatross banding data have been evaluated and survey designs
have been provided. Sarah Converse was recently hired to focus further
on manatees and albatross modeling and study design needs.
