Question 1

The Number of Hexagons Per Data Set

bir <-read.csv("/Users/surfaceLaptop2/Downloads/species richness csv files/bird layer.csv", stringsAsFactors = TRUE)
mam <-read.csv("/Users/surfaceLaptop2/Downloads/species richness csv files/mammal layer.csv", stringsAsFactors = TRUE)
rep <-read.csv("/Users/surfaceLaptop2/Downloads/species richness csv files/reptile layer.csv", stringsAsFactors = TRUE)

nrow(mam)
## [1] 63890
nrow(rep)
## [1] 63890
nrow(bir)
## [1] 63890

The Three Distributions of Data Sets

The three graphs here show the richness of each animal species.They show the native mammal, reptile, and bird count in California. The data is derived from the Statewide Terrestrial Native Species Richness Summary, Areas of Conservation Emphasis (ACE) provided by the State of California.

The Relationship Between Each Data Set

par(mfrow=c(1,3))
plot(m$NtvMamm, m$NtvBird, main="Mammals vs Birds", xlab= "Mammals", ylab="Birds", col="purple", pch=16, cex=1)
plot(m$NtvMamm, m$NtvRept, main="Mammals vs Reptiles", xlab= "Mammals", ylab="Reptiles", col="green", pch=16, cex=1)
plot(m$NtvBird, m$NtvRept, main="Birds vs Reptiles", xlab= "Birds", ylab="Reptiles", col="blue", pch=16, cex=1)

The three graphs demonstrates each species count and their relationship to one another. The graphs pit each species together to show how their count relate to one another. The California Department of Fish and Wildlife (CDFW) uses this data to determine the richness of the native species in California.

Question 2

Map of California
Map of California

This map demonstrates the richness of bird species in California. It appears the richest area with birds is near the coast of Northern California. The area that has the least diversity in bird species is towards Southern California on the border of Nevada.
