Biden-Harris Administration Held Offshore Wind Energy Auction

The Department of the Interior held the first-ever offshore wind energy auction for the Gulf of Mexico region, resulting in one lease area receiving a high bid of $5.6 million. RWE Offshore US Gulf, LLC was the winner of the Lake Charles Lease Area, which has the potential to generate approximately 1.24 gigawatts of offshore wind energy capacity and power nearly 435,400 homes with clean, renewable energy.

Live Feed at Bracken Cave

Bat Conservation International (BCI) and have launched the first-ever 24-hour live stream of the 20 million Mexican free-tailed bats roosting in San Antonio’s Bracken Cave, Earth’s largest known colony of bats. Viewers worldwide can now witness the jaw-dropping “batnado” — the emergence of millions of bats as they spiral out of the cave at dusk for their nightly insect hunts.

The RWSC Draft Science Plan is Available for Comment

RWSC Science Plan The Regional Wildlife Science Collaborative for Offshore Wind (RWSC) has released the Draft Integrated Science Plan for Wildlife, Habitat, and Offshore Wind Energy in U.S. Atlantic Waters for review and comment.

Canada's Ministerial on Nature

On August 23, 2023, on the margins of the Global Environment Facility Assembly meetings, Canada organized a Ministerial on Nature to advance global momentum on biodiversity and the implementation of the Kunming-Montréal Global Biodiversity Framework (KMGBF), following its historic adoption at the 15th Conference of the Parties (COP15) to the United Nations Convention on Biological Diversity (CBD).

Biden-Harris Administration Launches Water Recycling Program

The Department of the Interior announced the launch of a new large-scale water recycling program and made $180 million in initial funding from President Biden’s Bipartisan Infrastructure Law available for projects aimed at creating new water supplies that are less vulnerable to drought and climate change. The new program will incentivize projects at a larger scale, with no cap on project size, and will play an important role in helping communities develop local, drought-resistant water supplies by turning unusable water sources into clean, reliable ones.

October 2023 NABat Community of Practice call: Using Passive Integrated Transponders [PIT Tags] to Study Bats.

We'll be featuring two ongoing projects that have now surpassed the 10-year mark. Theresa Laverty with New Mexico State University will describe the collaborative effort to study patterns of habitat use and movement of Lesser Long-nosed Bats (Leptonycteris yerbabuenae) in the southwestern U.S. and Mexico. Jeremy Siemers and Rob Schorr with Colorado Natural Heritage Program will share their work investigating population dynamics of summer Little Brown Bat (Myotis lucifugus) colonies in northern Colorado pre- and post-Pd.
