Most species of willow and cottonwood <br />have good fire tolerance and resprout <br />readily after being burned as long as the <br />fire is not too hot. Many cottonwoods are <br />more susceptible to fire as they mature. <br />Other riparian species such as dogwood <br />and chokecherry also have a high fire <br />tolerance. <br />There may be times when native species <br />will not meet the landowners' objectives. <br />Introduced species should only be <br />considered in the revegetation plan after <br />careful review of the native sources (more <br />native species are available on the market <br />all the time), landowner objectives, and <br />disease and insect infestations. Refer to <br />the Idaho Tree Planting Handbook, North <br />Dakota Tree Handbook, and <br />Riparian/Wetland Project Infonnation Series No. <br />Species Distribution or Planting Design <br />19 for plant characteristics. <br />A planting design should be developed to show where each species is to be planted on the site. The entire <br />problem section should be planted, not just parts of a reach or curve. This will reduce the chance of water <br />eroding behind the planting. <br />Figure 2: Riparian Planting Zones can be used to determine where riparian species should be planted in <br />relation to the waterline. This is a general depiction of a riparian zone. Not all streams look like this one. In <br />the real world, some of these zones may be absent. (From Hoag 2001, Hoag and Landis 1999) <br />
