Document Summary
Forestry adaptation strategies: assisted migration, maintain corridors to facilitate natural migration, maintain a high diversity of age classes, thinning stands in drier area to conserve water, remove competitive species, develop drought-tolerant and insect resistant genotypes. If there"s access to tools, adaptation would be beneficial: no adaptations could be detrimental, communication between scientists and farmers needed, adaptation processes that farmers are using are going to define how climate change is impacting the yield. Temperature increase yield but only to certain extent. Overwintering potential: diseases: pathogens: high c:n ratio can favor pathogens as they like the sugar but reduced stomata opening, less entry points for pathogens, erosion, livestock (directly (heat, storm,) indirectly via effects on their feed, weeds, legumes. How can farmers minimize effects: adaptations, irrigation, hybrid, gmo, warning systems, education, crop rotation, buffer zones (erosion, water, pests, drought and/or heat resistant cultivars, change timing of snowing/harvesting, choice of crops, plant shade belts for livestock.
