Productive Conifers

The Forestry Commission recommends the best seed sources to be used to conifer planting and for most conifers, this seed source is located abroad and suitable for planting throughout the UK.  Alba Trees follows this expert guidance, sourcing the most highly improved seed from those recommended areas, but at the same time liaising closely with Forest Research to ensure that the seed is not known to carry any harmful pests or diseases: biosecurity is our top priority.

Productive Seed is classified according to its level of improvement:

Source Identified (SI): Comes from general of specifc locations within a single region of provenance or seed zone altitude band in which no specific superior qualities are recognised.

Selected: Collected from stands showing superior characteristics, e.g. better form, growth rate and health.

Qualified: Derives from the selection of superior individual trees which have not undergone any form of testing.

Tested: Derives from the selection of individual trees or stands that have undergone evaluation for genetic quality or have been shown to be superior, in comparison to accepted standards.

PSME_Luzette_SmallDouglas Fir La Luzette

The renowned ‘La Luzette’ seed orchard is suitable for most sites throughout the UK and will grow with better form and later bud burst.

 

 

PSME_Indigenous_SmallDouglas Fir Indigenous Stands

If you are not using improved stands, the FC has recommended the appropriate seed sources from the indigenous areas in North West United States.  We summarise the options here.

 

 

Norway_Spruce_Small

 Norway Spruce

Norway Spruce is often used as a good alternative to Sitka and tolerates wetter, more compacted soils than Douglas Fir.

 

 

 

SESE_Small

 The Redwoods

Both Coastal Redwood and Wellingtonia are good choices for warmer, wetter parts of the UK.  Although they can be frost tender, both are fast growing, deep rooting trees.

 

 

Cedars_Small

 Western Red Cedar and Western Hemlock

Fast growing and with naturally durable timber, both Western Red Cedar and Western Hemlock are becoming increasingly popular in Britain’s forests.

 

 

Productive Broadleaves

The Forestry Commission also recommends the best seed to be used when growing broadleaves for productive purposes and most of these sources are located within the UK.


Silver_Birch_SmallSilver Birch

There are new stands of Silver Birch now in commercial production and these should be used when timber or fuel wood are objectives.  Our factsheet gives recommendations about the best seed to use for your site.

 

 English_Oak_SmallEnglish/Pedunculate Oak

When growing English Oak with timber as a potential objective, it is important to choose the best available provenance to ensure optimal form and growth rate.

 

 

Sessile_Oak_SmallSessile Oak

Sessile Oak is often chosen as an alternative to Pedunculate for wetter areas.

 

 

 

Sycamore_SmallSycamore

With fast growth rates and good timber, Sycamore is a very popular choice in areas where squirrels will not damage the tree.

 

 

Wild_Cherry_SmallWild Cherry

Well grown Wild Cherry (Gean) can produce some of the most valuable timber of all the native broadleaves.  Our Wild Cherry orchards are progeny from the Wildstar project.

 

 

Native Forestry

Provenance_Map_smallWhen growing native forests, the Forestry Commission will ask that you use native seed sources.  The UK is split into 4 Regions of Provenance, which are further split into Native Seed Zones.  Often, the FC will ask that you plant trees which have been grown from a zone local to the planting site, but this should be considered against the potential effects of climate change and also against current availability.  Alba Trees uses a wide range of seed sources throughout the UK, so please discuss your requirements with us.

 

 

Caledonian Pinewoods

Caledonian Pine MapWhen planting Scots Pine for conservation purposes, there are fare stricter restrictions on choice of planting stock than for other native species and a local pine stand should be used.  Alba Trees stocks plants grown from the widest range of pine stands and has been involved in restoring Scotland’s ancient Caledonian Pinewoods for over 25 years.
