Conhecer a biomassa do bosque natural permite dimensionar seu valor ecológico e econômico; além disso, foco na perspectiva clara de convivência adequada. O objetivo do presente estudo foi calcular o armazenamento de carbono da biomasa, a situação do solo e os tipos de microorganismos descomponedores orgânicos do bosque natural no Cerro Escalera. Seccionado três lotes, al azar, no interior do bosque de 136 hectares, do Centro de Biodiversidade, administrado pela Universidade Nacional de San Martín, com latitude Sul -6.4607; longitude Oeste -76,2896; altitude 963 msnm. A mostra de mantillo foi analisada no laboratório de microbiologia de solos da Universidade Nacional de San Martín, para determinar a existência e o conteúdo de bactérias e fungos. A metodologia foi com diluições e siembra, em placas Petri, contendo meio de cultivo TSA (triptona soja agar) para bactérias; e, meio PDA (ágar papa dextrosa) para alimentos. Resultados, a biomassa seca do bosque natural pesa 127.849 kg ha-1 e armazena 58 t ha-1 de carbono orgânico. O solo mostra baixo conteúdo nutricional de nitrogênio (0,03%), fósforo (2,95 ppm) e potássio (53,9 ppm). O mantillo ostenta 13.833.333 unidades formadoras de colônias (ufc) de bactérias por grama de mantillo e 120.000 unidades formadoras de colônias (ufc) de hongos por grama de mantillo. Conclui-se que a biomasa do bosque almacena é de 58 t ha-1 de carbono orgânico, proveniente de 128 t ha-1 de biomasa.
