CONSIDER CWHvm1- East STAND / ECOSYSTEMS – In a changing climate

CWHvm1- East STAND / ECOSYSTEMS- 2050(PCM & HAD) SUMMARY OF DISCUSSION: Vulnerability Classes Low – Stands will suffer minor losses due to climate change. Mod – likely will suffer significant but manageable losses and or secondary risks (fire etc.) High – likely will suffer major losses or incur high secondary risks, but catastrophic losses unlikely. Very High – likelihood for catastrophic losses are high. Opportunity Classes Nil – No opportunity to enhance growth. Minor – Minor growth enhancement likely. Significant – significant growth enhancement likely. SpeciesVuln. Class Opp. Class Reasoning (e.g. drought stress/ HwLow-ModNilStill OK – may lose vigor on 03 south facing sites. SIBEC – could look at where these might occur. Lots of stand data on these 2 nd growth stands – Karel Klinka did lots of site index work – across range of site series. CwLow – some minor losses NilSomewhat the same as Hw

CWHvm1- East STAND / ECOSYSTEMS- 2050(PCM & HAD) SUMMARY OF DISCUSSION: SpeciesVuln. ClassOpp. Class Reasoning (e.g. drought stress/ BaMod-HighWill not be as happy in dm or xm conditions – will be restricted to cooler slopes and moister sites. Even plant little Ba here today. Sawfly problems up Philips Arm (also White, Eve, Adams drainages – Shoen Lake – TFL 39) – climate change may reduce these problems (warmer drier – may have few problems) FdLow to NilMinor - NilShould be coming into a climate regime that Fd will do well in – this will favour Fd. DrLowMinorNo issues – will still be moist – should be good Yc??? Hard to say – not much there

CWHvm1- East Ecol. Suitable Regen – Now and Future MESIC SITE DISCUSSION : 1.What are the vulnerabilities and why? (drought / insects / disease?) 2.What are the opportunities – where / when? 3.What are the outstanding questions?

CWHvm1- East Regeneration Vulnerabilities & Opportunities Added Comments: Fd – major opportunities for regen and growth. On sites here zonal to xeric – Pw will do well. On receiving sites Cw will still do OK Cw should likely be at least secondary Hw regen here is prolific except on brushy sites Hw on rich sites now –form is terrible fluted butt logs With considerable moisture – Hw should still be OK – just avoid rich sites. Likely decomposition to change soil fertility – likely not lots in next years – could check this out – lots of research now. Dr – careful where it is managed with outflows – but generally in this part of the mainland sites – don’t get these right now – it would have to change - problem – not the major inlets here. Likely not a huge issue Mesic Sites

CWHvm1- East Regeneration Vulnerabilities & Opportunities Added Comments: Dr = desirable to maintain on the landscape – diversity and improve site productivity on this moist warm sites. Ba – will be challenged – less summer moisture. North aspects might be OK if it is mixed with Cw (which would be favoured). Hybrid or native cottonwood – not poplar with foresters – need enough for a business. If we experience a great deal of change – may be a short rotation species (along with Dr) to allow for flexibility. Diversity on the landscape – probably best to keep it to where it naturally occurs on the landscape. Bitter cherry – short term species – lasts for 50 years. Comes in dense with banked seed but not a big competitor – may make its way into the vm1 as conditions change. Mesic Sites
