RATIONALE: For the last 30 years, the country has been experiencing the negative effects of ecological imbalance in the uplands caused by the worsening problems of resource depletion, environmental degradation, inequitable distribution and allocation of lands and natural resources, poverty in the upland, the continuous influx of lowland migrants (Developments in Agroforestry Research, PCARRD/DOST1997). Out of 6.5 million hectares of forest land of our country, forest degradation is accounted at 100,000 hectares annually (DENR, 1990).
The province of Palawan although considered as the last frontier is not far from that situation. Currently, many species of plants in the province are in the verge of extinction mainly because of man-made causes. Habitat destruction is the most serious threat to many of Palawan’s endemic plants. The most destructive of which is “kaingin” or slash and burn agriculture where large tract of forest lands are burnt to give way to upland agriculture. In the process, many plants are destroyed including indigenous or endemic plants.
To help in addressing the problem, the Department of Agriculture-Research Outreach Station, Palawan Agricultural Experiment Station (now DA-Palwan Research and Experiment Station) having the development zone of Hillyland, thought of proposing this project in order to preserve/conserve the endemic/indigenous plants in the uplands particularly those that bear fruits for fresh consumption and with medicinal value. There are also identified indigenous plants of banana species which shall also be given concern for they are soon to extinct. In 1998, collection of endemic citrus species had been started by the office and they are now growing and had started bearing fruits.
In this endeavor, it is with high hopes also that a material shall be published featuring some of the endemic collections of the province of Palawan since there are limited materials on this. Also, to have an area where they can be grown for future researches and conservation purpose, as well as source of plant materials should there be efforts to bring them back to the forest to contribute in balancing the ecology.
OBJECTIVES:
To conserve the different strains of endemic/indigenous plants in Palawan
To characterize each as to their pomologic and agronomic characteristics
To data bank gathered information/observation and publish information materials regarding the endemic plants of Palawan.
To serve as destination for educational tours and gene pool of different endemic plants of Palawan.
1. ESTABLISHMENT OF TWO GENEBANK SITES:
Palawan – known for its rich flora and fauna has unique bio-diversity. The province has two distinct climates – the southern side has most frequent rainfall and is considered the food basket of the province and the northern side having hot weather condition and tourism side of the province.
Southern side has agro-climatic condition different from Puerto Princesa that is the reason why two areas were considered for the establishment of gene pool and nursery of these plants – the DA-PAES area and the Rural Agricultural Center (RAC) Abo-Abo, Espanola, Palawan.
In DA-PAES, there are three planting sites,
a) at the backside,
b) within the multi-storey plants providing shade and climbing material to vine forming plants, and;
c) near the cashew area for the banana species.
2. Collaboration activities such as: Meeting with LGU’s such as Municipal Agriculturists, Barangay officials and Indigenous People to help identify the possible source of these plants in their areas.
3. After which, land clearing followed as part of the preparation for crop establishment for two sites.
Initial activities conducted were collaboration with LGUs such as Municipal Agriculturists, Barangay officials and Indigenous People to help identify the possible source of these plants in their areas. After which, land clearing as part of the preparation for crop establishment was conducted. Preparatory activities for two sites are as follows:

4. Leaf characterization was also conducted. Some fruits were also evaluated to determine their Total Soluble Solids (TSS) or degree of sweetness. They are also further evaluated for their economic value.
For the two sites, more than 3 hectares are being maintained serving as gene pool of this project.
5. Some seedlings were potted for distribution in 2014. Collection of seeds and seedlings are still being done in preparation for treeplanting next year. The activity has been collaborated with the Palawan Council for Sustainable Development.

OUR NEW COLLECTION
Palaw Sagit-sagit, grows luxuriantly among the vine plants, Tabo on the other hand has stunted growth. The plan of transferring it is being considered.
OTHER ACCOMPLISHMENTS:
1. CENRO requested more than 500 plants for their replanting activity in Brgys.Luzviminda and Mangingisda.
Also requested that they will be part in our tree planting plan for 2012.

Through the help of Dr. Lerum of WPU
At present more or less 518 indigenous/endemic plants of different species had been planted to more or less 3.0 has in two sites.
These plants will be one of the attractions once the DA-ROS, PAES will open the office to be the new destination of tourists in the province of Palawan.

1. Funds should be provided for the maintenance of these collections. These are very precious plants which form part of the rich biodiversity of the province and should be protected for our future use and generation next to us.
2. Other government agencies can help in the
identification of new sites for expansion particularly those whose thrust is on the protection of our forest natural resources.
3. Promotion as exotic food. All fruits can be made
into wine and some can be made into jams and jellies, the DA-ROS, PAES and WPU have processing facility where Research and Development section can find ways on how these plants can be processed for value adding.
