| Measuring drought and drought impacts in Red Sea Province |
|8. Changes in tree density on five sites in Red Sea Province: early 1960s to 1989. Roy Cole|
Substantial negative changes in the density of trees were measured on three study sites. a moderate decrease was found on one study site, and a slight increase was found on one study site in Red Sea Province. The cause of the decline in tree density is probably related more to human activities than drought, however, the effects of drought were impossible to measure given the degree of change attributable to human land use activities.
