Re: Russ Forest Lidar

I'll have to find where these often cited metroparks are and look at their LiDAR canopy heights. SE Michigan has full LiDAR coverage.

Re: Russ Forest Lidar

Any notable tree that happens to be near a field site, I will attempt a measurement, if I am aware of it. Officially, that could be anywhere in the Lower Peninsula down to northwest Indiana, east to northwest Pennsylvania. That said, my fieldwork has been fairly limited in range range in the last fe...

Russ Forest Lidar

I visited Russ Forest Park in Cass County, MI in 2012 and saw the remnants of a tuliptree (Liriodendron tulipifera) allegedly 60 m (200 ft) tall. The log on display was not convincing, and I was unable to find any trees that came close to that size. This was before I had a laser rangefinder. I found...

Re: Climate constraints on maximum tree height

I have strong doubts on Baffin Island and Nome, Alaska having 50 m trees, LOL.

Climate constraints on maximum tree height

This paper analyzes correlation among different functional traits and climate, including maximum tree height. I have not uncovered where they get the maximum height by species, and I question the taxonomic accuracy of their source for geographic distribution data in GBIF. It also doesn’t seem to add...

Re: Michigan datbases entries

Michigan datbases entries

I recently visited Fabius State Game Area in St. Joseph County. Though many of the game areas are fairly cut up and invaded by multiflora rose and garlic mustard, there are a few nice stands. One such stand includes a tuliptree that I initially measured at 39.0 m tall with my laser hypsometer. But e...

Blandford Nature Center - Grand Rapids, MI

Today, my son and I rode our bikes to the Blandford Nature Center on the west side of Grand Rapids, armed with a DBH tape and a Nikon laser rangefinder. I have been curious about the baseline height of forest canopy around the city of Grand Rapids, and the height of the apparent tallest trees. Along...
