Arid and semi-arid areas are not exempt of this rule. Arid and semi-arid areas of northeast Iran cover about 3.4 million ha and are populated by two main tree species, the broadleaf Pistacia vera (pistachio) and the conifer Juniperus excelsa ssp. polycarpos (Persian juniper). Natural stands of pistachio in Iran are not only environmentally important but also genetically essential as seed sources for pistachio production in orchards. We investigated the relationships between tree density and vegetation indices in the arid and semi-arid regions in the northeast of Iran by analysing Advanced Land Observing Satellite (ALOS) data PRISM is a panchromatic radiometer with a 2.5 m spatial resolution at nadir, and has one band with a wavelength of 0.52—0.77 um (JAXA EORC). AVNIR-2 is a visible and near infrared radiometer for observing land and coastal zones with a 10 m spatial resolution at nadir, and has four multispectral bands: blue (0.42—0.50 pm), green (0.52—-0.60 um), red (0.61—0.69 jum), and near infrared (0.76—0.89 um) (JAXA EORC). In this study, we estimated various vegetation indices using maximum filtering algorithm (5x5) and examined. This study carried out of juniper forests and natural pistachio stand using Advanced Land Observing Satellite (ALOS) and field inventories. Have been compared linear regression model of vegetation indices and proposed new vegetation index for arid and semi-arid regions. Also, we estimated the densities of juniper forests and natural pistachio stands using remote sensing to help in the sustainable management and production of pistachio in Iran. We present a new vegetation index for arid and semi-arid regions with sparse forest cover, the Total Ratio Vegetation Index (TRVI), and we investigate the relationship of the new index to tree density by analysing data from the Advanced Land Observing Satellite (ALOS) using 5x5 maximum filtering algorithms. The results for pistachio forest showed the coefficient regression of NDVI, SAVI, MSAVI, OSAVI, and TRVI were (R2= 0.68, 0.67, 0.68, 0.68, and 0.71) respectively. The results for juniper forest showed the coefficient regression of NDVI, SAVI, MSAVI, OSAVI, and TRVI were (R2= 0.51, 0.52, 0.51, 0.52, and 0.56) respectively. I hope this research can provide decision of managers to helping sustainable management for arid and semi-arid regions in Iran. 1. INTRODUCTION Arid and semi-arid areas of northeast Iran cover about 3.4 million ha and contain two main tree species, the broadleaf Pistacia vera. L (pistachio) and the conifer Juniperus excelsa ssp. polycarpos (Persian juniper), which are found at different elevations above sea level (a.s.l.) (Figure 1). Persian juniper forms open woodlands, with a maximum tree density of approximately 150 trees per hectare (pers. obs.; Andrew et al. 1996). This species is found from Turkey to Afghanistan and east and south to Iran (Fisher and Andrew 1995) and at elevations ranging from 1500 to 2900 m a.s.l., and is also found In Pakistan, where it is fairly common, forming open forests in Baluchistan and inner dry valleys of the Himalayas from 1200 to 4000 m (Andrew et al. 1996). However, the climate at these altitudes may be marginal for the survival of Persian juniper, and even small increases in climatic stress could imperil the present status of these woodlands (Fisher and Andrew 1995). Pistachio is thought to have been cultivated for 3000-4000 years in Iran. Currently, Iran is the world’s largest producer of Pistachio, followed by the United States, where most pistachio Production is in California. In 2004, Iran and the United States Were responsible for 44% and 13% of global pistachio ey T1” Corresponding author. Tel.: +81-45-778-5605; fax: +81-45-778-5706.

Most pistachio production in Iran occurs in orchards, but there are a few areas, such as in northeast Iran, where wild pistachio (Pistacia vera L.) grows in natural stands, mostly at elevations of 500-1200 m (a.s.l.). Natural stands of pistachio are important, not only environmentally but also genetically as seed storage for pistachio production in orchards. In addition, natural pistachio stands, which are managed by the Natural Resource Organization of Iran, provide rural residents with opportunities to obtain extra income by participating in harvesting. ocations of the study areas in northeast Iran
