Wildlife and Habitat Conservation

• 22-year-old nonprofit conservation organization with nearly 50,000 members in all 50 states, Canada and several countries, including more than 3,000 wildlife biologists and natural resource professionals

• 180 Branches in 35 states and Canada

About the QDMA

National Headquarters & Education Center

QDMA Mission“To ensure the future of white-tailed deer, wildlife

habitat and our hunting heritage.”

Current National Issues/Trends

Whitetail hunting generates over 50% of the entire$67 billion U.S. hunting industry

“Whitetails are the backbone of the U.S. hunting

industry!”

Four times more hunters hunt deer than the next closest species

There are numerous current and potential threats to whitetail herds and hunting

Available online at: QDMA.com

Economic & Industry Impacts

Expenditures by deer hunters represent 53% of all hunting expenditures

Deer Population Trends From 1985 to 2005, the U.S. whitetail population

doubled from 14 to 30 million

Decreased Wildlife Agency Budgets and Services

Can’t do more with less money and staff

Increased Private Wildlife Services

Wildlife consulting is growing as the number and needs of recreational landowners is increasing.

Increased Private Ownership of Recreational Lands

In fact, from 1991-2006, the number of hunters purchasing land increased 56% and now exceeds 1.34 million throughout the U.S.

Increasing Involvement in QDM and Habitat Management on

Private Lands

Without question – these are the “Good Ol’ Days”

The approach under which young bucks are protected from harvest combined with an adequate harvest of female deer to produce healthy deer herds in balance with existing habitat conditions.

What is Quality Deer Management?

It is NOT Trophy Management!

Prescribed Fire and QDM:Opportunities and Barriers

Four Cornerstones of QDM

Prescribed Fire can be a Valuable Tool for Managing:

1) Hardwood Stands2) Pine Stands3) Old Fields

Many landowners’ hardwood forests look like this…

Managing Hardwood Stands for Wildlife

But, they can look like this…

Growing-season fire- September – October- reduces woody understory- stimulates herbaceous cover- best adapted to drier sites- every 3 – 5 years

Dormant-season fire- reduces litter- stimulates woody sprouting- dry or relatively moist sites- every 3 – 4 years

Fire Timing and Frequency

Fire may damage hardwoodsFire may damage pines also!Low intensity is key!Don’t burn to mineral soilBurn with moist duff layerMove debris from around trunk

Comparative Results:

Adjust the composition- kill undesirable plants- promote desirable plants

Maintain successionPrescribed fire

- 2 – 5-year interval- alternate seasons

Disking- on quarters- season of disking

Herbicide applications

Managing Old Fields for Wildlife

The Perfect Composition…

Barriers to Increased Use of Prescribed Fire by Private Landowners

#1 -- Fear! 1) Uncontrollable wildfire

2) Damage – property, structures, neighboring property, etc.

3) Liability

4) Smoke management

5) Unknown

When / Where Did This Fear Originate?

#2 – Lack of Awareness of Value- Continued education and outreach

#3 – Lack of Training - Increased training opportunities for private landowners

#4 – Lack of Awareness of Available Resources (e.g., GFC)

Other Barriers
