This is horrible coming from an animal advocate but I won’t go into that now. My family is buried at the cemetery I go there often I do not want to hear gunshots or witness a deer being killed by a bow in a place I go for peace of mind. I also don’t see many deer I am in area often so the report is not believable.
The DCR report estimates 67 deer per square mile of deer habitat.
The DCR report estimates that deer habitat is 80% of total area.
So the DCR report calculates that there are 67/0.8 = 85 deer per square mile of the total area (simplifying the calculation).
Due to the widespread use of the land (by hikers, dogs, cyclists, park ranger vehicles, busy roads), an additional number is required to show how human activity lowers the area available to deer.
A value of 20% for human disruption factor would lead to a number of about 17 deer per square mile.
Also, the estimated value of deer habitat could be as high as 90% which would lead to 67/0.9*0.2 = 15 deer per square mile.
Another outcome of the human disturbance factor is that deer will concentrate along preferred routes, to avoid human contact, and they will follow these trails fairly closely, probably using scent to guide them. It is therefore likely that some homes that are close to these deer trails will experience higher numbers of deer, while other users of the park will not see the same concentration of deer.
Hi Steve,
I’ll forward your calculations to DCR — and your contact info.
Thanks for your comment!
I would be interested in bow hunting around the blue hill area. I have a son that attends curry college that is looking for landowner permission to hunt the milton area.
There is a mistake in their survey – their estimate of the deer population in the Blue Hill reservation is far too high. The real number is less than 5 deer per square mile using the Hahn line method.
Steve – I’ll let the DCR know about your comment. Thanks for taking the time to read and respond!
Steve,
The Mass Fisheries and Wildlife staff said that “the Hahn method is an outdated and severely negatively-biased technique for estimating deer numbers. Even without the deer survey data, the habitat impacts on and around the reservation provide more than enough data to inform us that deer numbers are high.”
He also suggested you look at the deer study online: http://www.mass.gov/eea/docs/dcr/parks/south/blue-hills-deer-survey-report.pdf
Hope that helps!
Haven’t seen more than 30 deer in more than 20 years of hiking around the Blue Hill. The deer count/survey report’s numbers are not believable – perhaps there were some repeat counts during they survey. Do you have access to the original survey forms? A blank form is shown in the report with no observation data – the report would be more believable (or not) if it included copies of the raw data.
