Tree Progeny

Tree Progeny. . , Forest tree improvement is by its very nature a long-term endeavor and requires a continuing commitment of resources to be successful....[it is] an investment that can pay broad dividends in forest adaptability and productivity in the face of dramatically changing environments and climates. , Paul Bloese, Tree Improvement Supervisor , Department of Forestry, Michigan State University , , In 2021 and 2022, red pine trees were planted here and in the two plots to the west. They are part of a Michigan State University (MSU) 50-year genetic test using seed produced by 22 mother trees. , , Seedlings (progeny) are genetically similar to their mother trees. Scientists monitor their growth to assess whether traits like height and diameter are influenced by genetics or the environment. , , The Process , Foresters select seeds from good genetic stock to plant at nurseries. Once the seedlings grow enough, they will be transplanted into Michigan's state forests. , , Scotch Pine Orchard , This photo [lower right] was taken at MSU's Tree Resource Center in East Lansing. Researchers look for answers to questions such as why one tree is smaller than its neighbors. , , Lower left image caption: In 2021, tiny seedlings were planted in long straight rows here at the historic Higgins Lake Nursery site. , , Upper right image caption: In 2022, foresters measured the distance between seedlings to allow room for growth.
