Its wood products division recorded pre-tax profits before special items of US$64m. Higher average lumber realisations were partially offset by lower realisations for OSB and lower productivity for engineered wood products.

Wood products sales volumes declined compared to the Q4, 2013, due to severe weather and transportation challenges due to Canadian rail car and trucking availability.

Weyerhaeuser expect "significantly" higher earnings from the wood products division in Q2.

"Despite unusually severe winter weather, we delivered strong operating results in the quarter," said Doyle Simons, president and chief executive officer. "Our Timberlands business is realising increasing benefits from the Longview Timber acquisition and reported its highest quarterly earnings excluding land sales since 2006. We are relentlessly focused on driving operational excellence in each of our businesses to grow a truly great company."
