treeblog update: the Set C downy birches (November 2011)

Downy birch No. 1: too branchy!

This is the first update of the Set C downy birches (Betula pubescens) since May! There are now twelve Set C birches altogether: Nos. 1, 2, 4, 5, 10, 14, 15, 21, 22, 23, 25 & 27; No. 13 has unluckily died since May. I took the photos this afternoon – 970 days or 2 years & 8 months since I planted them all as seeds.

Downy birch No. 2: lovely form and the tallest of the lot at 47 cm.

No. 4: almost-straight stem (apart from that one kink).

No. 5: the second shortest at 22 cm tall.

No. 10: super-straight stem.

No. 14: average.

No. 15: nice, straight stem and the second tallest at 43 cm.

No. 21: doesn’t want to let go of those leaves.

No. 22: nice, straight stem with a strangely disproportionate branch.

No. 23: decent stem above the kink.

No. 25: the runt of the litter; very poor form and by far the shortest at 6 cm tall.

No. 27 – good stem.

The Nature Conservancy’s Plant a Billion Trees initiative

The Nature Conservancy is raising money to restore a million acres of the Atlantic Forest in Brazil by planting a billion trees by 2015. The initiative is very close to passing the 10 million mark. If you’d like to make a donation, one dollar will see one tree planted. To find out more and donate, visit plantabillion.org
