Learn More & Start Drafting Your Plan

Reccommended Readings and Activites:

  1. Walk through your woods and observe your forest with forest health in mind. Take pictures and notes of the following:
  • Overcrowded stands where tree crowns are touching and in stressed conditions.
  • Areas of blow-down and fallen trees. How many trees are fallen and what species are they? What direction did the trees fall? How did they fall (uprooted, stem break, etc.)?
  • Areas of damaged tops (from wind, snow, or ice)
  • Evidence of drought damage
  • Other signs of forest health issues (insect evidence, disease evidence, animal damage, dwarf mistletoe, etc.)

Start drafting the Overview, Insects and Diseases, and Environmental Factors subsections of Forest Health/Wildfire/Invasive Species section (Resource Category 1) of your plan. Use the Forest Health Examples as a guide. Try to identify any priority issues and steps to take to address them. You will likely need to wait for your site visit to confirm any diagnosis and finalize this session. Note: the invasive species and fire risk portions of this section will be addressed later in the course.
