Collect seeds in Wisconsin for us

Are you looking for a fun activity for yourself or your family this fall? Why not spend some time helping the Wisconsin reforestation team fill our seed coffers.

The Wisconsin state nurseries have been producing seedlings since 1911. In that time, there have been many changes in personnel, growing techniques and distribution methods. However, something that has remained constant is the source of those seedlings: Wisconsin seeds. The vast majority of seedlings produced at the Wisconsin state nurseries originate from seed collected from native trees. From the tiny, pepper-like seed of aspen to the large, husky black walnut, the reforestation staff at the nurseries collects, cleans and stores hundreds of pounds of more than 30 varieties of native tree and shrub seed every year.

While we are able to satisfy some of our needs, we rely heavily on members of the public to collect for us as well. For those interested in becoming seed collectors, we publish a newsletter every fall. Information on seed collection and the 2017 Seed Collector’s Newsletter can be found on the DNR website. Our staff is always available to answer questions about seed collection or any other reforestation topic.

Head outdoors this fall. You will be amazed at how much fun it is to crawl around in the woods for a few hours picking up acorns or walnuts!

Wisconsin Community Tree Map release

The DNR’s Urban Forestry program is excited to unveil a mapping application which provides a new way of viewing and learning about trees in your community. Wisconsin Community Tree Map is a browser-based application that maps community tree inventories. This means no special software is needed to run the application.

Preparing your site for tree planting

Now is a great time to start planning for tree planting next spring and site preparation is a critical component of that planning. During the end of the growing season, while the landscape is in full bloom and lush, landowners are better able to visualize opportunities to develop wildlife habitat, provide visual barriers, and improve aesthetic qualities on their property. These timely observations and some research will provide the necessary information to determine how newly-established trees will impact their property.

Event will highlight wood-based construction

Advancements in wood technologies have expanded the use of wood in design and construction. Mass timber products such as cross-laminated timber (CLT) have emerged and offer opportunities in tall wood construction. The Wisconsin DNR, in partnership with the Wisconsin Wood Marketing Team, Forest Stewards Guild, and the American Institute of Architects, will host a seminar on September 20, 2017 in Madison, Wisconsin to highlight wood-based construction, mass timber products, applicable building codes, and case studies on how wood technologies can be a sustainable, cost-effective solution for tackling modern design needs. The event will feature a tour of “The Crossroads” located on the Promega campus, showcasing an innovative mix of glulam and cross-laminated timber.

Architects, engineers, designers, developers, general contractors and others interested in wood design are encouraged to attend this informative seminar to be held at the Promega Corporation’s BioPharmaceutical Technology Center (5445 E. Cheryl Parkway, Madison, WI 53711).  The registration fee of $30 ($15 for students) includes lunch and refreshments.  Visit the event webpage for online registration and additional information.  

**Event fulfills 4.5 AIA/CES credits**

Venturia shoot blight in northern Wisconsin

Venturia shoot blight has been observed throughout northern Wisconsin this summer. Venturia shoot blight is one of the most common fungal diseases of aspen and is favored by cool, wet spring weather. 

The pathogen rapidly kills expanding terminal and lateral shoots, causing shoots to wither and droop. It also causes leaf necrosis, appearing as black circles of varying sizes, necrotic curling at the margins, or complete leaf death. The disease is most damaging to seedling and sapling aspen, where it can reduce height growth and cause temporary stem crooking as lateral shoots are released and compete for apical dominance.  Disease control is unnecessary in a forest setting.
