Once the pine cones are collected, they're brought to a network of nurseries, where the seeds are extracted and grown into seedlings. One million seedlings will plant about 4,500 acres of new forest.
On the coast, the knobcone pine may hybridize with bishop pine (Pinus muricata), and Monterey pine (Pinus radiata). In the western foothills of the Sierra Nevada, knobcone pine is often a co-dominant with blue oak (Quercus douglasii).

Raw or insufficiently composted wood chips can crust over in summer making water penetration difficult. The active microbes in the soil that chomp away at those fresh chips can tie up lots of soil ...

Level III subdivides the continent into 182 ecoregions; of these, seven lay partly within Arkansas's borders. Level IV is a further subdivision of Level III ecoregions. There are 32 Level IV ecoregions in Arkansas, [2] many of which continue into adjacent areas in the neighboring states of Oklahoma, Mississippi, Missouri, Louisiana, Tennessee ...
AGFC officials said the agency will have collection stations around the state where people can drop off their trees. The trees will be used as fish habitat in local lakes. Arkansas Game & Phished ...
