Hidden Hazards in the Canopy Preventing Animal Bite Risks in Tree Care By Mara Watts
you’re assessing thoroughly for haz- ardous animals,” she said. As part of the assessment, crews should take the time to scan the ground and the tree itself. For exam- ple, if raccoons are a concern, look for signs of hollowed cavities in the tree where nests may be tucked in- side. If you happen to find this, Thi- erbach said to perform a hazardous report on the tree.
From furry creatures tucked away inside hollowed cavities to scaly and slithery reptiles hiding amongst the rocks and swamps, arborists regular- ly encounter various animals. What a jobsite is to us is a home to them, and it is understandable that when these creatures feel danger, they’re prone to defend themselves with what na- ture has equipped them with — their teeth. While some bites — like those that don’t break skin — can amount to nothing more than a surprise and a Neosporin-coated bandage, other more substantial bites can lead to se- rious bodily injury, allergic reaction, or disease transmission. And all bites should be treated with the same cau- tion and care. The good news, though, is that most bites are preventable with the right knowledge, awareness, and effective use of protective personal equipment (PPE). In this article, we’ll walk through several of the most common animals associated with biting hazards for ar- borists, their typical behaviors, warn-
ing signs to watch for, and related tools and equipment to help protect you from a bite. Note: Keep in mind that this is not an exhaustive list. The great outdoors is home to many more hazardous and potentially risky animal encounters. So, it’s important to research and un- derstand the specific wildlife thriv- ing in your region, so you can stay prepared and aware on every job site. BUT FIRST, PERFORM A JOB-BRIEFING Before work begins, Dawn Thier- bach, ISA Certified Arborist and co-proprietor of Victori- an Gardens, a full spec- ORM ns, Dawn Thier- fied Arborist of Victori- l spec- hrub sed an, trum tree and shrub care company based out of Michigan, emphasized a few practical ways that crews can assess a work site or tree for potentially problematic animals. w at a for ematic “You’re supposed to be doing a job briefing anyways, so just make sure to be doing a job j t k
Most animal bites are preventable with awareness, proper PPE, and a thorough job briefing.
