Agroforestry systems offer an alternative for integrating production, biodiversity conservation, and socio-ecological resilience in the Amazon. The study aimed to assess the agricultural components and plant diversity of the agroforestry system at the Lucero farm (Teniente Hugo Ortiz parish, Pastaza, Ecuador) to support strategies for production and environmental improvement tailored to local conditions. A descriptive, observational case study was conducted. The agricultural component involved georeferencing and delineating productive areas, technical field walks, direct observation, and a semi-structured interview with a producer, alongside the recording of management practices, fertilization, disease issues, and production yields. The forestry component was evaluated across three 20 × 20 m plots—totaling a sampled area of 1,200 m²—where 35 individual trees were recorded. Parameters determined included dasometric variables, species richness, relative abundance and frequency, dominance, Importance Value Index, Shannon-Wiener and Simpson indices, evenness, and the Composite Conservation Index. The farm covered an approximate area of 470,000 m² and featured diversified agricultural production—predominantly cacao—alongside nutritional and phytosanitary limitations. Diversity and structure varied across plots; Shannon-Wiener values were 0.695, 0.669, and 0.579 for plots P1, P2, and P3, respectively. Based on the assessment, agroecological intensification, assisted natural regeneration, selective enrichment, and adaptive monitoring were proposed as management strategies, the effectiveness of which should be evaluated in the future.
