HWA monitoring

From now until mid-April is the best time to monitor for HWA. The woolly balls will be clearly visible until May or even later, but after mid-April there's some danger of inadvertently moving crawlers to new areas (see life-cycle). Here's a survey protocol for citizen monitoring in Ontario (largely based on New York and Pennsylvania protocols, and including some inaturalist photos): http://www.ancientforest.org/wp-content/uploads/HWA-detection-handout-Ontario.pdf and a great handout showing look-alikes: http://www.ancientforest.org/wp-content/uploads/HWALookAlikes.pdf
