Last month, Eli Sagor introduced me to the MyMinnesotaWoods team and I’m excited to be aboard! In my new role with the U of M Department of Forest Resources and Extension I’ll be addressing forest ecosystem health issues for forest landowners and natural resource professionals across Minnesota.
A recent report by Steve Shifley and colleagues from the US Forest Service caught my eye. They outline five anthropogenic factors that will alter northern forests within the next 50 years. Not surprisingly, some of these factors include how invasive species will impact forests, the trends in expanding urban areas, and low forest diversity. As a relatively new resident of the state, this report got me thinking about how having clear management goals and adequate planning can help to maintain a healthy and productive forest.
Let’s be realistic: maintaining a sense of optimism can often be difficult when planning for and adapting to the myriad threats to our forests. This summer alone, the state has imposed a gypsy moth quarantine, confirmed emerald ash borer in a new county in southeastern MN, and spruce budworm has shown up again with strong numbers in St. Louis County. Despite this, we can think about strategies that seek to manage these various threats to maintain or increase the resiliency of our forests.
The report outlines four basic management actions that land managers can take to address these factors. Using Minnesota as an example, we can see how we are currently addressing these actions and highlight new opportunities for maintaining resilient forests:
1. Develop goals for forest diversity
Like any good plan, developing a list of benchmarks or goals can help to identify a successful management strategy. For measuring diversity, we can think about how a woodland or forest ownership meets several benchmarks. A few of these benchmarks include identifying the species found in your forests, understanding the age of the forest, and documenting its structure and general tree size.
2. Better understand urban forests and their role in a changing landscape
Minnesota is a unique state in terms of its vast (and economically important) forests, farms, and urban areas. All forests, whether in wilderness or in an urban setting, provide valuable ecosystems services through their ability to provide clean air, clean water, and sequester carbon. As pointed out in the report, the economic value of the ecosystem services that urban forests provide are tremendous. Such annual ecosystem services are valued between $233 to $456 million in several large metropolitan areas.
Key management concerns of urban areas are (1) to identify where future urbanization is likely to impact forests, (2) to sustain urban and community forests for the ecological values they provide, and (3) understand how forest health may be impacted by changes in land use. Tools such as the MN Geospatial Information Office’s land use and land cover data products will be important in examining the role of urban forests in a changing landscape.
3. Develop conservation goals across all forest owners
Forests managed solely for the timber they provide lose value when timber markets are down. Instead, managing forests holistically for the the goods and ecosystem services they provide increases the likelihood of managing a sustainable forest.
We publish on nontimber forest products and forest stewardship issues on a regular basis at this site. Looking forward, we will continue sharing these topics. We also hope to gain more unique perspectives on how different forest owners and managers are tackling various conservation goals.
4. Work together to understand how forests are changing
Managing a single acre of woods may be easy to implement and monitor. Things get complex when multiple ownerships with contrasting management strategies and goals are considered collectively. In other words, how are management actions promoting resistant and resilient forest ecosystems at a landscape level?
Such an example of working together in Minnesota can been seen in the Manitou Collaborative established by The Nature Conservancy. Comprised of county, state, federal, and private ownerships in northeastern MN, the Collaborative seeks to sustain timber products, enhance wildlife habitat, and retain scenic beauty across the Manitou landscape.
How are you carrying out these management actions for your ownership or lands that you manage?
