One key observation about this ecosystem is the fact that it is currently being overrun by a growing population of Strawberry Guava, a highly productive type of plant that uses up the groundwater around it, leaving less for native species and ultimately killing them. Another observation about the forest is the ratio of native to non-native species. In 2013, students of Mililani High School observed the amount of native species to non-native and found that there was optimistically more indigenous than non-native plants in the area. In 2012, a recorded number of 7 native snails was found to dominate the 2 invasive Rosey Wolf snails. However, the same investigation was repeated this year and sadly found that there was only 5 native snails and 4 Rosey Wolf snails. This data shows that the number of invasive snails increased within two years, while the number of native snails found was reduced within those years.
