Coillte and the Benlowe Group are the latest timber firms to sponsor the Wood for Gold campaign through its new funding scheme.
Both companies have become bronze sponsors, meaning they will contribute £3,000 to fund its work.
Arnold Laver was the first company announced under the initiative, becoming a gold sponsor by stumping up £20,000.
Forestry company Coillte owns and manages 445,000ha of land in Ireland, around 7% of the country’s land mass, while Leicestershire-based Benlowe manufactures a range of timber doors, windows and stairs.
The sponsorship system was developed after discussions between Wood for Gold and timber firms.
Gold status requires a £20,000 donation, silver £10,000 and bronze £3,000.
