This paper reveals the relationship between critical loads of nitrogen on seven most common types of vegetation (annual grassland, coastal sage scrub, desert scrub, chaparral, pinyon-juniper woodland, oak woodlands, and mixed conifer forest) present in California. According to this paper, critical loads is the threshold which substantial negative impacts do not occur. This paper reports that for nitrogen, studies shown that 35% of the land areas with these vegetation types exceeded the critical load. In order to determine the area with excess nitrogen, the studies used multiple methods, such as lichens because it is nitrogen-sensitive and vegetation that was nitrogen deficient. Consequently, vegetation types experience several significant changes and chaparral is not an exception. This review educates the

Cavitation has a decreasing impact on plants’ ability to transport water from the soil to their leaves. The studies report that plants in chaparral vegetation are more susceptible to cavitation during the wet season. The studies also found that the location (for example, temperature, precipitation rates or distance to the coast) of chaparral have impacts on cavitation resistance. In addition, the studies hypothesize and found that plants in chaparral habitats with greater precipitation have the tendency to become less resistant to cavitation, especially in the beginning of summer. This paper is relevant to chaparral because it explores the relationship between cavitation in chaparral vegetation and its effects on the overall
