La Molina is one of the districts with the bigger green areas and ecological awareness in the city of Lima. The Universidad Nacional Agraria La Molina (UNALM) represents about half of the green areas in the district; being the Schinus molle L. «molle serrano» the second most abundant tree species in the campus and one of the most planted in Lima. This native tree with recognized cultural importance is widely used in the arboriculture crops for its ornamental and rustic character, resistant to the drought and plagues; whose top formed by hanging branches offers shade and when having a fast replacement of foliage, it is able to filter the air capturing particles in suspension and CO2. However, it has been observed the presence of burls along the shaft and branches in trees of this species altering its ornamental character and representing a probable risk. Therefore, the internal structure of the tree was studied using the Arbosonic 3D forest tomograph and/or the resistance of healthy wood, wood with burl and wood with rot by means of the physical and mechanical properties of the wood: basic density (DB), resistance to bending or modulus of rupture (MOR) and rigidity or modulus of elasticity (MOE). The results determined the absence of Schinus molle L. tree risk due to the presence of burls, evidencing the importance of the use of the forest tomograph in the management of arboriculture crops in Lima.
