Managing Agricultural Land to Benefit Streaked Horned Larks: A Guide for Landowners and Land Managers

This document is designed to be used by conservationists and private landowners as a guide to management of agricultural land to benefit streaked horned larks. The range and population size of this rare grassland bird has shrunk significantly over the last century as the habitats that it historically occupied have largely been converted to agricultural pursuits. Streaked horned larks are currently listed as a Candidate for federal protection under the Endangered Species Act, as Critically Sensitive in Oregon, and Endangered in Washington. Streaked horned larks favor sparsely vegetated areas, and agricultural land can be managed in several ways to provide good lark habitat. The guide will focus on management in Oregon’s Willamette Valley, but the principles should apply to management of agricultural lands in any portion of the larks’ range.
