Biodiversity has 3 components – ecosystem, species and genetic resources
Best way to conserve plant biodiversity is to protect and maintain them in their natural habitats – in situ conservation
However, biodiversities in their natural habitats are always under threat and are, in fact, being lost at an alarming rate.
For this reason, research institutions have come to the rescue, albeit quite late.
They collect economic plant species, including related species and their genetic resources, and establish and conserve them in gene banks – ex situ conservation.
Farms and home gardens can also actively participate in plant biodiversity conservation - on-farm biodiversity conservation.
The RC Fruit Conservation Farm is a strong advocate and active practitioner of on-farm biodiversity conservation.
INTRODUCTION
Ecosystem Diversity
Ecosystem. The complex of a community and its environment functioning
as an ecological unit in nature. Forests, deserts, mangroves and marshlands are well-defined ecosystems.
Caves are also considered an ecosystem.
Farms and home gardens, properly managed, are important and useful
ecosystems. Each ecosystem has its own microclimate and a set of flora and fauna.
COMPONENTS OF PLANT BIODIVERSITY
Species Diversity Worldwide, there are more than 1000 tropical fruit species on record.
In RP, more than 300 edible fruits and nuts are grown. Only about 30 are economically useful; the rest are underutilized and unutilized.
Species diversity within a genus is important in varietal improvement and vegetative propagation.

BIODIVERSITY CONSERVATION SYSTEMS
In Situ Conservation
For fruit species, forests are the safest sanctuary for permanent conservation of plant resources.
However, forests are being lost at an alarming rate and with them are lost valuable plant resources.
Illegal logging Agricultural development Urban development
Fortunately, man recognizes the importance of collecting and conserving plant resources in safer places.
Ex Situ Conservation
Plant resources are collected and kept in seed and field gene banks.
Gene banks are established in research centers like IRRI, PhilRice, NPGRL-IPB, etc.
Ex Situ Conservation
Seed gene banks are very costly to established and maintain.
Field gene banks require a large growing area, vulnerable to typhoons and destructive pests.
Long-term life depends on long-term funding.
If not sustained, gene banks may be poorly maintained or even close (e.g. DA Lamao Expt. Sta., Limay, Bataan).
On-farm/ Home Garden Conservation
Also an in situ conservation system
Can serve as duplicate repositories of germplasm collections conserved in research centers.
Elite collections (e.g. cultivars and hybrids, heirloom plants) are usually grown.
Some farms and home gardens also collect and grow underutilized species.
FRUIT BIODIVERSITY CONSERVATION AT THE RC FRUIT CONSERVATION FARM (RCFC FARM)
Description The RCFC Farm was acquired in 1986.
A 4-ha gently rolling land at the foot of Mt. San Mateo, Imok, Calauan, Laguna.
A neglected coconut farm of old, unproductive palms (RC Farm)
While the coconut was being rehabilitated, outstanding varieties of rambutan and langsat or lanzones were Inter cropped (RC Fruit Farm)
Over the years, (25 years) numerous fruit and nut species from local and foreign sources from the tropics of both hemispheres were collected and established (RC Fruit Conservation Farm).
Focus has shifted from commercial fruit production to fruit biodiversity conservation, promotion and plant material and information dissemination.

CONCLUDING REMARKS The RCFC Farm plays an active role in on-farm biodiversity conservation.
It is the first and perhaps the only one in the Philippines.
It hopes to contribute to the global effort in plant biodiversity conservation at the farm level.
This is relevant and meaningful in the Philippines where numerous economic plant species are being constantly threatened with extinction.
And their rich and valuable genetic resources are being severely eroded every year.
