Mae'r Tasglu hefyd wedi ystyried pa newidiadau sydd eu hangen ar draws y gadwyn cyflenwi pren i annog y maes adeiladu i ddefnyddio mwy o bren a ffibr o Gymru. Yn groes i rai canfyddiadau, mae Cymru'n gallu tyfu pren o ansawdd uchel ac mae cyfle i gynyddu faint o bren o Gymru a ddefnyddir mewn meysydd uwch eu gwerth. Mae hyn yn gofyn am fwy o gydgysylltu ar draws y gadwyn gyflenwi er mwyn sicrhau bod cyflenwad sefydlog o bren o Gymru, bod gennym sector prosesu arloesol, a bod galw sefydlog gan ddefnyddwyr terfynol fel Cymdeithasau Tai.
The Task Force has also considered what changes are required across the timber supply chain to encourage greater use of Welsh timber and fibre in construction. Contrary to some perceptions, Wales is capable of growing high quality timber and there is an opportunity to increase the amount of Welsh wood used in higher value added areas. This requires a strategic approach to coordination across the supply chain to ensure there is a stable supply of Welsh timber, an innovative processing sector, and stable demand from end users such as Housing Associations.
