Silviculture Agroforestry Regime: Compatible Management in Southern Gunung Merapi National Park, Java, Indonesia

Silviculture agroforestry regime (SAR), which is a compatible management with forest rehabilitation and also
renewal zoning system of the national park, was started to increase the agroforestry productivity surrounding
Gunung Merapi National Park (GMNP). In addition, SAR also supported the basic information succession of
Mount Merapi eruption in 2006 to strengthen Merapi lava tour. This is an innovative step in developing GMNP,
in which its pro-poor conservation is not only based on land productivity, but also based tourism. This study was
begun with the development of a permanent plot to study succession (May 2008-Novemper 2009), and the
impact of community intervention on grass stock at GMNP, as well as to assess agroforestry typology and its
implication on the areas surrounding GMNP. SAR was developed using landuse model based on limiting the
factor of each agroforestry cluster. Choosing the treatment in SAR refers to the actual condition and opportunity
every agroforestry cluster and sensitivity analysed until the intervention on the GMNP was minimal. The
implementation of SAR was done with a software known as Stella 9.0. There are five SAR models which are
appropriate for agroforestry cluster (AF); these are labelled as AF1-SAR1, AF2-SAR2, AF3-SAR3, AF4-SAR4
and AF5-SAR5. SAR is based on resources sharing whereby space is arranged through crown pruning and also
rationalization number of dairy cows. In addition, SAR has a packet management for synergizing function of
private lands (homegarden, dry field and land village as a unit management) and intensification by land tillage,
renewal of grass and fertilization. In particular, SAR1-5 has the ability to balance agroforestry management with
decreasing local community intervention and increasing biodiversity level on GMNP. The ratio for grass
productivity outside GMNP with grass necessity and implementation of SAR was close to an optimum point (1).
Meanwhile, the ratio values of SAR1-5 were 0.982, 1.010, 1.44, 1.047 and 1.253, respectively. Nonetheless, the
implementation of SAR needs more technology of silviculture agroforestry and a full support from stakeholders.
