Summary

Potential pollinator habitat was derived by ranking land use classifications and grassland quality based on ground truthing and remotely sensed features indicative of remnant prairie. High resolution (10m) land use data served as the basemap (Hartley et al 2017) from which most categories were identified. All known prairie remnants, prairie plantings, and clusters of mima mounds were delineated. Mima mounds were detected by deriving a slope at 1m scale with greater than 5% from high resolution LiDar data (3m). Mima mounds are indicative of areas in which the topsoil has not been significantly disturbed, and therefore have a higher potential to contain native prairie vegetation. Based on an in-depth literature review of pollinator ecology, [...]

Purpose

Over the past few decades, there has been a significant loss of pollinators, including honey bees, native bees, birds, bats, and butterflies (Committee on the Status of Pollinators in North America 2007). The problem is serious and requires immediate attention to ensure the sustainability of our food production systems, avoid additional economic impacts, and protect the health of our ecosystems. On June 20, 2014, President Obama issued a Presidential memorandum entitled “Creating a Federal Strategy to Promote the Health of Honey Bees and Other Pollinators.” In response to the President’s memorandum, the Louisiana Federal Pollinator Partnership was formed by the USGS, EPA, NRCS, and the FWS. The partnership is working together to protect, enhance and restore pollinator habitat in Southwest Louisiana using a multi facet approach including public education and outreach, public-private partnerships, and best science and information available to inform the process Some of the USGS objectives within this partnership is to develop spatial datasets which identify areas of source pollinator populations, and rank areas to target for pollinator enhancement projects within the historical range of coastal prairie.
