If you want to learn more about all the amazing uses of bamboo and how to grow it, you are invited to join the Hawaii Chapter of the American Bamboo Society at noon July 24 at the Kona Cloud Forest Sanctuary in Kaloko Mauka.
The address is 73-1865 Hao St. and the sanctuary is adjacent to Mountain Thunder Coffee Mill. Just use your GPS or call Jacqui Marlin, president, at 966-5380 for meeting details. It is a potluck, so bring your favorite dish.

More than a hundred species of bamboo have been planted at the sanctuary to test their adaptability. Even though most species are at their best in sunnier and wetter locations such as East Hawaii, many high elevation species are doing quite well in Kaloko Mauka.
Global warming is no longer a theory and is being accepted as fact by most scientists and governments. This will affect our Islands by causing more extremes such as drought, floods and severe storms.
We might not be able to do much about other parts of the world, but here at home we are either part of the solution or part of the problem. If each one of us on the Big Island planted just 10 clumps of bamboo or trees this year, we would have planted more than 1 million.
That can make a big difference, since trees and tree-like bamboos not only produce oxygen, but they supply shade, act as windbreaks and lock up the carbon that is the main cause of global warming. Some of the best bamboos for that purpose are the giant Dendrocalamus that can reach heights of 100 feet and more.
Many species of clumping bamboo, such as the genus Bambusa, are much shorter and better for smaller gardens. There are some species that range from a few inches tall to several feet tall and fit well in miniature landscapes.
Since there are more than 1,200 species of bamboo, it’s a good idea to get in the know with the bamboo society.

Many of Hawaii’s forests and forest watersheds are threatened, even with all the rhetoric about saving rain forests.
We just returned from Borneo, where native forests are being cleared for agriculture. Not much can be done to stop foreign governments from forest destruction, but we can do a lot to protect and plant forests here.
In East Hawaii, many ohia forest areas are subdivided into small lots of 1-3 acres. Unless the owners of the land really commit to protecting the forested lots, they are bulldozed and flattened. In West Hawaii, the same situation occurs with private lands being subdivided and cleared.
One exception is the Kaloko Mauka forest. This is one of the most accessible native forests in West Hawaii. It, among other high elevation areas of Hawaii, is being developed for agriculture and residential activities. However, county planners are making an effort to encourage developers and landowners to protect the forest by placing requirements that the lots remain in forest.
The county also is requiring a forest management plan and is allowing owners to dedicate land to native forest or tree crops, thus reducing the tax burden. Information about how to apply for agriculture and conservation dedications can be obtained from the Hawaii County tax office.
Some developers are concerned about forest protection and are incorporating these requirements into their plans. They have set an example of Hawaiian land stewardship that others throughout the county are beginning to follow.
Although the main plantings are eucalyptus species, it is hoped they will continue efforts to include other species such as koa for long-range, high-quality forest products. Those folks opposed to eucalyptus might consider that it is closely related to ohia.
In West Hawaii, much of Kaloko Mauka is still covered with native forest. Although it is sparsely populated, the gardens of residents are a fascinating mixture of hydrangeas, hoawa, calatheas, camellias, koa and kopiko. The area abounds with ancient ohia (Meterosideros polymorpha) and gigantic tree ferns, some of which are 30 feet or more in height. These ferns can be more than 100 years old since the trunks only grow 2-3 inches per year.
The native forest contains many rare and endangered species that local residents are committed to protect through the Hawaii Forest Stewardship Program. This program allows residents to dedicate and manage their properties to enhance this important and unique watershed. It is administered by the state Department of Land and Natural Resources Forestry Division.

In the heart of the subdivision, the 70-acre Kona Cloud Forest Sanctuary was set aside for testing palms, tree ferns, bamboos, bromeliads and other plants. Observations are being made as to their adaptability for reforestation, agricultural and landscape use.
Most of the sanctuary is preserved in native forest. The mauka 5 acres was damaged by grazing and removal of ohia and hapuu in the 1960’s and was reforested in native and non-native trees to create a pantropical forest. The upper 10 acres was totally cleared in the past and now is reforested as a montane tropical forest and includes koa, ohia and conifers from the high tropics.
Efforts at the sanctuary are to protect and preserve native plants and animals. At the same time, the sanctuary is testing and using non-indigenous plant materials that are “environmentally friendly” — that is, plants that will not displace native plants but are able to exist in harmony, adding fruit, fragrance and color where desired.

Kaloko Mauka is the home of the Hawaiian hawk, apapane, iiwi, elepaio, amakihi and many other endemic and exotic birds. Kaloko Mauka was identified as essential wildlife habitat and forest watershed.
It is the goal of residents of Kaloko Mauka to set an example that they can live in harmony with the forest and still have homes and some forest-friendly agriculture activities. This is essential if our island is to have the rainfall and watershed needed to supply communities at lower elevations.
Some folks think East Hawaii has plenty of rain, so forests are not necessary. However, forests are like big sponges. They slow down flooding rains, and give up moisture so streams continue to run when rainfall is light. Without forests, flooding and drought as well as severe erosion becomes the norm. Also, grassy weeds are notorious fire hazards during drought times.
Tropical forests include not only trees but understory palms, bromeliads, orchids, ferns and bamboos. Many palms worldwide are endangered because of the destruction of rain forests. Fortunately, Hawaii is becoming a kind of Noah’s Ark thanks to the efforts of the Hawaii Island Palm Society, bamboo society, orchid societies, rhododendron society and other concerned groups.
Not only is it vital to protect our remaining Hawaiian forests, but to reforest those abandoned cane lands of Hamakua, Puna, Ka‘u and Kohala with biodiverse forests, ensuring valuable resources for future generations.
