Dream team to work with + had time to visit a cathedralesque Douglas breeding arboretum planted in the 60s with the first round of British selections

We are marking up forward-selected Douglas firs in "US85" progeny tests in Mortimer forest and collecting cambium samples for genotyping

@LGuillardin great - will be interesting to hear about it at some point. we measured the one in the west of England in January if that would be useful to you? no disease in it yet though..

Three days sampling cambium from larch trees. 370 samples from different provenances. Here how we did it: silica gel in a falcon tube and a tea bag inside the tube. Samples were drying until we got to the lab and took the sgel out and put the tube in the -20c. #forest #genetics

At Northern Research Station we've sown 10 provenances of Scots pine from across Europe (see map)🌲 So far they're growing well! After another growing season they'll be planted at two multispecies common gardens in the UK as part of a wider European network @OptFORESTS

Controlled (polymix) pollination of Scots pine - very efficient this year in @ForestryEngland's well managed seed orchard @ForestProtectUK (though it's only about 50 metres into England)

Rapid flowering in one year from a couple of spruce grafts - both with fairly precarious looking unions

This is the first Sitka spruce graft from the below multi-provenance stiffness (modulus of elasticity) selection campaign to flower on the nursery. This tree's parents are/were from Naden Harbour, Haida Gwaai

Selecting candidate 'plus trees' in a range-wide @IUFRO provenance trial of Sitka spruce today in northern 🏴󠁧󠁢󠁳󠁣󠁴󠁿. In January, these trees will be felled, assessed for acoustic velocity and the best ones will be cloned to build up an elite population for stiffness @Forest_Research

Our "temporary storage shed for cones" AKA the pagoda, immortalised in FC Bulletin 83 (1992) is being retired after ~50(?) years of service and replaced with a new one. £millions of genetic gains have passed through it's arches
