Dear HWC community,
I'd like to share with you a challenge highlighted by my colleagues of the WWF Arctic programme and hope you might have any suggestions!
In various Arctic communities we've helped to set up so called polar bear patrols. These people help keep villagers safe from polar bears wandering around. They escort children to school, help reduce attractants and scare a way bears that are coming too close to the settlement.
The idea to temporarily mark bears that are coming near communities came up. This would help the patrols understand whether the same individuals keep coming back, with how many bears they're dealing in a season, and to identify which are actually the 'problem bears'.
However, there are concerns that colour marking on the bear's coat would disadvantage the bear's ability to hunt if it makes them stand out more against their background. Also there are culturally related concerns, such as a reduced skin value for sale by Inuit communities.
There are also challenges related to the actual administration of the paint onto the bear in an easy and safe way. Paint bullets are often not very accurate which can lead to hitting vital organs or the animal's head.
So the question is twofold:
1. Are there types of paint that can be easily washed off (but will not wash off when a bear takes a swim), or perhaps fluoresent under UV light or similar?
2. What would be the best way to adminster the paint only a polar bear which has not been sedated?
Loking forward reading your responses!
