I spent the better part of the last two days measuring trees for the state register. I bought the nikon 440 rangefinder and I am blown away by it's accuracy and ease of use. Optics planet had it for $186 with free shipping. Megan will inherit my old Bushnell so we can get some more info out of Delaware.

Haverford College Arboretum, founded in 1833 by the Quakers, called and asked if I would come out and measure some trees for consideration. The already had a couple on the list. Most of the trees were planted in the 1920's. The fellow helping me rounded all the heights to whole numbers. It costs $42,000 a year to attend this college!!

Abies firma                        6.6x70.8 most of the firs had the same scale as the hemlocks
Abies chensiensis               8.3x70.0
Abies fargesii                     4.4x57.0
Abies holophylla                2.1x24

Tsuga caroliniana               3.6x40.0 adelgid free, but ravaged by scale
Tsuga diversifolia               3.1x30.0 same as above

Picea asperata                   6.1x45.0
Picea sitchensis                  6.9x38.0
Picea mariana                    5.5x37.0
Picea polita                        5.8x49.0
Picea obovata                    3.9x57.0

Pinus parviflora                  7.6x74.0
Pinus flexilis                        4.6x62.0
Pinus cembra                      4.3x42.0
Pinus taeda                         7.2x66.5 second largest in the state

Hamamelis virginiana          2.2x19.3

Quercus rubra                   24.4x100x102   new state champ at 418 points. has a low branch, but is not a coppice. was just over 100' tall.

Today I went to Taylor Arboretum in Wallingford. I was amazed to see species that I have never even heard of. Most trees were planted in the 1950's. They had three trees on the list that I needed to remeasure, and as usual, there were more to be had.

Pinus sylvestris                  7x59.7
Cornus controversa           6.3x40.3
Juniperus rigida                  3.4x40.8
unknown fir                       6.9x81.4
Hovenia dulcis                   4.0x62.2
Quercus accutissima          10.0x90.1
Acer davidii                       5.9x58.7
Idesia polycarpa                7.3x63.2

That ought to keep you busy googling names for a while ; )
