Biomass

The amount of vegetation on Kauai has always impressed me. Except for tomatoes which we always have difficulty finding at Farmers' Markets, it must be a great place to grow crops. The challenge would be finding a plot of land as any open space is quickly inhabited. On the other hand, I feel bad for the professional gardeners and the crews who trim back the Guinea Grass by the sides of the roads. Something always needs to be pruned or pulled or picked up and removed. 

According to my quick research on the topic, the amount of growing stuff is due to its unique geographic and climatic conditions. This island’s vegetation is a direct result of its volcanic origin, which provides nutrient-rich soil. This richness is derived from the breakdown of volcanic rock, which releases essential minerals and creates a soil structure that retains both moisture and nutrients effectively. It doesn't look like Iowa soil but it must be good.

Kauai’s climate is a second factor. The island has a tropical climate, characterized by warm temperatures throughout the year. However, the most significant climatic factor contributing is its extraordinary rainfall. It rains a lot everywhere on the island. However, Mt. Waialeale, one of the wettest spots on Earth, receives an average annual rainfall of about 450 inches. This amount of precipitation ensures abundant water resources.

Here is an example.

I was walking on the beach near our cottage and I saw this plant with a long single vine snaking across the sandy soil. Freaky looking. There was an area of open ground and a plant moving quickly to take advantage.

I took a closer shot and used Plantsnap (an app on my phone) to request an identification. The common name is Beach Morning Glory.
