Important Bird Areas

Columbia Bottomlands

Texas

The Columbia Bottomlands are characterized by the mixed hardwood forests stretching across the floodplains of three major rivers (Colorado, San Bernard, and Brazos) and their associated bayous. This site covers most of counties (Brazoria, Ft. Bend) and part of another two (Matagorda and Wharton). These forests extend southward to within 6 miles of the Gulf of Mexico and represent the best bottomland stopover habitat in Texas.

Ornithological Summary

This site is used by over 240 species of birds each year. Dr. Sidney Gauthreaux (Clemson University Radar ornithology lab) has used local radar stations to estimate habitat use by migratory birds and has estimated that this site hosts approximately 29 million birds each year. This includes species of concern such as: Swainsons, hooded, prothonotary and worm-eating warblers, Bell's vireos, olive-sided flycatches, swallow-tailed kites and bald eagles.

Ownership

Due to the size of the site, contacting private landowners is unfeasible except through a press release. However, USFWS, TPWD and TNC all own and manage land in the site and area aware of the nomination.
