Black Vultures

New Regulations on Black Vulture Control


New regulations have come into play that may allow a producer who currently is suffering the effects of depredation caused by Black Vultures to kill up to 5 Black Vultures per year. The Virginia Department of Agriculture and Consumer Services (VDACS) and the Virginia Office of USDA-Wildlife Services have secured a process (with approval from the US Fish and Wildlife Service, the agency that holds ultimate regulatory authority) by which affected producers can acquire a sub-permit that allows for this lethal take. 

For additional details, visit the VDACS website at Black Vulture Depredation and Control ( Questions about this new program should be directed to Chad Fox, coordinator of the USDA-WS Vulture Damage Control Program (540-381-7387 or

Virginia Agriculture Cost Share (VACS)

Cost Share funding is available from the District! These funds provide financial assistance for agricultural landowners and operators to implement best management practices on their properties in order to improve soil and water quality. If you have a natural resources concern on your farm, now is the time to talk with district staff about developing a plan to address these concerns! We can provide cost-share funding for practices to help:​

  • decrease soil erosion on crop and pasture land

  • exclude livestock from waterways

  • implement nutrient management plans

  • adopt new precision nutrient application technology

  • establish tree plantings or vegetated buffers along streams

  • plant cover crops

  • construct manure storage or chemical storage facilities

  • construct feed lots/sacrifice areas

  • continue to practice no-till planting


In order to qualify for cost-share, your farm must meet the following:

  • Property has/had a water quality concern (e.g. livestock has/had access to a waterway, manure is washing into a waterway, there are no cover crops when main crops aren’t growing)

  • Property must have at least 5 consecutive acres

  • Property has been in agriculture production for the past 3 years

  • Property has produced at least $1,000 worth of agriculture products/year (agriculture products include crops, hay, and livestock, such as cattle, equine, sheep, goats, llamas, alpacas, etc. Horses solely for personal use are not considered as agriculture products.)

  • Property is located in Prince William County (if your farm is outside Prince William County, contact your local soil and water conservation district; to find your district, click here.)

If you feel you have a need to implement these practices on your farm, or have any questions about the cost-share program, please contact us:

Market Maker from Virginia Cooperative Extension (VCE)

As more and more people want to buy their food fresh and locally, Market Maker is an upcoming way to connect farmers with their customers. Market Maker is an online portal where customers can search for farms, farmer's markets, specific agriculture products, etc. that are near by. Farms can also sign up on the portal so customers can better find them. Market Maker is free for both farmers and customers.

Nutrient Management: An Important Message for Producers

The 2025 Chesapeake Bay cleanup goals are here, and we need every farmer's help! We need documentation of implementation of every nutrient management plan in Prince William County. Here's what you can do to help:

  • Work with your nutrient management planner to develop a plan that can be implemented easily

  • Keep application and yield records

  • Put in place a record-keeping system so you can justify application and yield data.This must include required elements such as dates, field locations, loads, bales, bushels, gallons of manure, tons of litter, etc.

  • Share this record-keeping system with your planner.

  • Update your plan as changes occur on the farm.

  • Be prepared at the end of the growing season to evaluate how well you were able to follow your plan.


If you have questions, please contact your nutrient management planner:

(571) 379-7514
