We just published a 20-page white paper of mapping for Arborists and other tree pros. It explains what tools – many free – are available now to quickly get field data and convert that to nice maps for clients. It also establishes how things like “GIS” and “CAD” files work (or don’t) with one another,[…]
Here is a 9-minute run-through of the field interface for Urban Forest Metrix, the system designed for arborists and tree care firms. This demonstration concentrates on the iPad interface elements for field technicians looking to work with trees, do mapping, conduct tree risk assessments and various other functions.
With raptors, unlike some birds, their risk factors for death don’t diminish much once they leave the nest. The danger really just starts. They must learn to hunt and navigate any number of hazards. One of my neighbors, a male broad winged hawk of about 7 weeks of age met his demise in front of me,[…]
This past winter, we spent some weeks trying to pin down the location of a bobcat den in our back forest. It was an exhilarating chase that I likened to a game of Battleship, where we would place game cameras in the forest at some locations based on educated guesses, and once we got lucky[…]
It has now been more than a week since we last saw the Cooper’s hawk fledglings. Weather intervened, taking a few days off of our camera regimen, and then the loon project stole our attention. But five days ago, three days ago and again today, I took a camera and an iPad into the forest to[…]
With the Forest Metrix cameras trained on the loon nest and its environs, we get to see the foggy transformation from night to day and couldn’t resist processing the images into a timelapse. Note the lily pad flowers at the bottom of the screen opening up at the end.
In a lake near Forest Metrix’s offices, a pair of loons started nesting for the first time in a number of years. They didn’t pick a particularly good location, it seems, putting their eggs a couple inches above a mud bar formed at the mouth of a creek. Locals alerted the Vermont Center for Ecostudies, which employs[…]
Yesterday was day 31 of the Cooper’s hawks’ first hatching. A lot has happened in the past 7 days, since the last update. As I suspected, soon after the last update, they fledged. I was up in the tree when I believe it first happened, although it could be that this was just a reprise[…]
The last image I have of the smallest chick is from Tuesday the 21rst a bit after 2 p.m. It wasn’t doing well, sleeping much, not appearing terribly successful in the food scrums, and suffering from some sort of wound on the back of the neck. For the previous week or so, it didn’t seem[…]
To see earlier posts on the Cooper’s hawk project, see these links: Update 1 Update 2 This third update recounts events starting on June 18, 2016. June 18: The larger of the young are just at that tween stage, where they are about to look more like hawks than hatchlings. It happens, very, very rapidly,[…]
