History Petrified Forest National Park is located in the Painted Desert in northeastern Arizona taking up 93,532.57 acres of its land. Before the national park was established, it was founded as a National Monument on December 8, 1906 when President Theodore Roosevelt signed the proclamation. Years later, the Congress passed a bill and established it as a national park on December 9, 1962. Centuries before Petrified Forest National Park was preserved as a national park, the land was preoccupied by
shelter for small reptiles and mammals such as lizards, snakes and the spinifex-hopping mouse. Another example of a coastal plant is the Atriplex, also known as the salt bush. The saltbush grows in the form of a shrub, and develops triangular-shaped leaves. Blooming season for the salt bush is from the middle of spring to the middle of summer. The Atriplex is an important source of food for wildlife such as elk, deer and rabbits. Q2: What is one natural cause of coastal landscape degradation?
More than 40 species, native to the Eastern Sierra, of flowering herbs, grasses and shrubs were planted in beds surrounded by a natural vegetative community of perennial shrubs including, big sagebrush (Artemisia tridentata) and four-wing saltbush (Atriplex canescens). The amount of water this past year likely revived many species
Effects of salinity on plants Definition: Salinity is the state of high salt concentration or it can be define as the presence of minerals at high levels in water and soil. For example, there are some cations: Na, K, Mg, Ca and anions: NO3, HCO3, SO4, Cl, which accumulates in soil at high concentration and cause salinity in that soil. Introduction: Salinity is major a biotic factor that reduce growth and yield below optimum level. Salinity is the global issue that results in osmotic stress and reduction
