DNR shipping trees; last chance to purchase seedlings

DNR’s reforestation program is busy harvesting seedlings from our nursery fields and shipping them to woodland owners throughout the state. If you own forest land in Wisconsin and still need seedlings for planting this spring, contact Carey Skerven (carey.skerven@wisconsin.gov) as soon as possible or call the Wilson Nursery (608-375-4123) in Boscobel or the Griffith Nursery (715-424-3700) in Wisconsin Rapids. We will do our best to fill your orders.  Here are the species still available as of April 3:

Conifers: Jack pine 1-0, red pine 2-0, white pine 2-0, tamarack 2-0, and white cedar 3-0.

Hardwoods: Aspen 1-0, river birch 2-0, butternut 1-0, black cherry 1-0 and 2-0, hackberry 1-0, bitternut hickory 2-0, shagbark hickory 3-0, hard maple 2-0, red maple 2-0, silver maple 1-0 and 2-0, red oak 2-0, and black walnut 1-0.

Shrubs: Chokecherry 1-0, ninebark 1-0, and American plum 1-0.

Managing seed orchards for tree improvement

Soon after the beginning of the nurseries in Wisconsin, managers realized they had a special role to play in the development of trees, especially when it came to disease resistance, growth, and form. In conjunction with the UW system, USDA Forest Service scientists and researchers and our own tree geneticist, nursery staff established a number of seed orchards.  Throughout the decades, we have explored and invested in new sites, creating a tree improvement program that is stocked with species in various stages of development and/or characteristic selection.

Reforestation monitoring update

2016 was the second season reforestation staff have use the revised protocol for monitoring reforestation sites. Due to ample rainfall and warm weather, the seedlings across the state are performing very well. This fall we are looking at sites that have gone through 3 and 7 years of growth and have visited 25 sites so far.

Transline® herbicide trial begins

In keeping with the Reforestation Program’s mission of providing pertinent information to forestry professionals, we began a new herbicide field trial with Transline® (clopyralid). Many foresters and landowners are interested in applying herbicides after a site has been planted to inhibit weed competition. However, in the case of Transline®, not all species are referenced on the label. In addition, the varying rates prescribed may impact species differently. All of this can create a challenge for a forester or landowner when managing competition within the planting. Continue reading “Transline® herbicide trial begins”

Herbicide testing in nursery environment

Over the course of several years of monitoring new plantings on landowner properties throughout the state, reforestation staff encountered a wide range of herbicide prescriptions, with varying results. Often, staff encountered trees showing a high degree of stress, or even mortality, which appeared to be linked to the herbicide application.  The decision was made to test some herbicide treatments in our nursery to see how stock reacted to the chemical at various rates and application timings, under more controlled conditions than what is typically found on outplanted stock.  We selected Dupont Oust XP (Sulfometuron Methyl) as our test chemical, since it is the most widely used pre-emergent herbicide currently in use in Wisconsin.

Greenwood students plant class tree

Every spring, the nursery receives an order for Arbor Day seedlings from Greenwood Elementary.

Nothing unusual there since the reforestation program provides more than 35,000 free seedlings to 4th-grade classrooms throughout Wisconsin every spring. What caught our attention about this order is that each year it included an additional request: a single hardwood seedling.  We caught up with the local DNR Forester, Chris Schmitz stationed in Neillsville, to ask about this unique outreach project in Clark County.

Team looking at natural regeneration issues

The Division of Forestry created a Natural Regeneration Ad Hoc Team to review and recommend natural regeneration monitoring protocols in an effort to provide a more cohesive statewide strategy for achieving successful natural regeneration. Forest regeneration was identified as an implementation issue in the Division’s Strategic Direction. Forest regeneration monitoring was also identified as an opportunity for improvement in forest certification audits on state lands.

Words of inspiration from reforestation staff

During the seedling lifting season each spring, it has been a tradition at the Griffith Nursery to offer inspirational words and thoughts to the staff on a dry erase board in the employee break room. Drawing on witticisms from famous athletes, authors, political figures, and comedians seems to provide a bit of levity during an often stressful time.

This past spring, one of the quotations struck a chord with me, as it put a much-maligned tree species into a different perspective:

 “The jack pine grows to any shape that suits the light, suits the winds, suits itself.”

~ Milton Acorn

Find the light. Lean into the wind. Survive. Thrive. Be the jack pine!
