🌿 Understanding the Biodiversity Crisis in Oil Palm Landscapes

Oil palm plantations have become a cornerstone of global agriculture, producing palm oil that finds its way into everything from food products and cosmetics to biofuels. Native to West Africa, the oil palm tree (Elaeis guineensis) thrives in tropical climates, particularly in Southeast Asia where Indonesia and Malaysia account for over 85 percent of the world's supply. However, the rapid expansion of these plantations has come at a steep environmental cost. Since the 1990s, millions of hectares of tropical rainforest have been cleared to make way for uniform rows of oil palms, leading to significant habitat fragmentation and biodiversity loss.

Biodiversity, the variety of life in an ecosystem including plants, animals, microorganisms, and their interactions, is particularly vulnerable in these monoculture landscapes. Tropical rainforests, which oil palm often replaces, are among the most biodiverse habitats on Earth, harboring species like orangutans, Sumatran tigers, and countless endemic birds and insects. Studies indicate that oil palm plantations support only about 10-20 percent of the species diversity found in natural forests. For instance, bird populations can drop by up to 80 percent, and large mammals struggle to survive due to food scarcity and lack of cover. This loss extends beyond species counts; ecosystem services such as pollination, pest control, and soil fertility also decline, affecting long-term plantation productivity.

The scale of the issue is staggering. It is estimated that oil palm expansion threatens habitats for 54 percent of globally threatened mammals and 64 percent of threatened birds. In Indonesia alone, deforestation linked to palm oil contributed to over 166,000 hectares of forest loss in the first nine months of 2025. While economic benefits like employment for millions of smallholder farmers are undeniable, balancing production with conservation is essential for sustainable development. This tension has spurred global initiatives, certifications, and research aimed at reconciling agricultural needs with ecological integrity.

The Landmark Study in Ecological Solutions and Evidence

A recent publication titled "Pathways to strengthen biodiversity protection in oil palm landscapes," featured in the journal Ecological Solutions and Evidence, offers fresh insights into this complex challenge. Led by Dr. Sarah Scriven from the University of York, with collaborators including Dr. Jennifer Lucey from the University of Oxford's Nature-based Solutions Initiative and Dr. Helen Newing from Oxford's Interdisciplinary Centre for Conservation Science, the study bridges academic research and industry practice.

Funded by the Roundtable on Sustainable Palm Oil (RSPO) through the SEnSOR program, the research involved in-depth interviews and surveys with 18 sustainability managers from 12 palm oil companies operating in Malaysia and Indonesia. These countries represent the epicenter of oil palm production, where vast concessions intersect with biodiverse hotspots. The study's strength lies in its grounded approach, combining practitioner experiences with scientific evidence from programs like the South East Asia Rainforest Research Partnership (SEARRP).

Published in early 2026, the paper emphasizes that while standards like RSPO require the protection of High Conservation Value (HCV) areas—regions critical for biodiversity, rare species, or cultural significance—and High Carbon Stock (HCS) forests, implementation gaps persist. Dr. Lucey noted, "To achieve real conservation impact, we need to bridge the gap between research and practice." This work provides a roadmap, highlighting that effective protection demands not just technical fixes but also social equity and economic viability.

Key Barriers to Effective Biodiversity Management

The study pinpoints several interconnected barriers that hinder conservation in oil palm landscapes. First, technical challenges dominate: many plantation staff lack expertise in biodiversity monitoring, leading to inconsistent data collection. Methods vary widely, from camera traps for mammals to acoustic surveys for birds, but without standardization, trends in species populations or habitat health are hard to track.

Social factors are equally critical. Unclear land tenure and insufficient involvement of Indigenous and local communities undermine efforts. Free, Prior, and Informed Consent (FPIC), a principle requiring community agreement before operations affect their lands, is often inadequately implemented. This erodes trust and participation, essential for long-term stewardship.

Economically, justifying biodiversity investments to senior management proves difficult. Short-term yields overshadow long-term ecosystem benefits, and integrating monitoring data into adaptive management—adjusting practices based on evidence—is rare. As Dr. Newing observed, "Protecting biodiversity in palm oil landscapes depends as much on respecting community rights and participation as on technical conservation measures."

• Limited staff training in monitoring techniques
• Weak community engagement and FPIC processes
• Inadequate data use for decision-making
• Challenges in demonstrating biodiversity's business value
• Lack of landscape-scale coordination among companies

📈 Evidence-Based Pathways to Enhance Protection

Drawing from company insights and broader literature, the researchers propose 15 actionable recommendations across four themes, offering a comprehensive framework for improvement. These pathways emphasize integration of people, processes, and practices.

1. Respecting Human Rights: Prioritize FPIC and empower communities in management. This includes mapping traditional lands and co-designing conservation plans, fostering ownership and reducing conflicts.

2. Standardizing Biodiversity Metrics: Adopt consistent indicators like species richness, habitat cover, and ecosystem function metrics. Shared protocols enable benchmarking and progress tracking across plantations.

3. Building Capacity: Invest in training for staff and auditors on field methods, data analysis, and HCV assessments. Knowledge-sharing platforms among companies can accelerate learning.

4. Improving Sustainability Processes: Enhance transparency via public reporting, implement adaptive management cycles, and pursue landscape-scale collaboration. Partnering beyond concession boundaries protects migratory species and corridors.

Dr. Scriven highlighted, "This research provides a clear, evidence-based roadmap for how companies can strengthen biodiversity outcomes while meeting sustainability standards." Implementing these could transform oil palm into a model for agroecological balance.Read the full study for detailed guidance.

Real-World Examples of Conservation Success

Practical applications abound. One promising strategy is establishing "tree islands"—clusters of native trees within plantations. A 2023 Nature study found that larger, more diverse tree islands boost native tree diversity by up to 50 percent and enhance ecosystem functioning without reducing oil palm yields. In Sumatra, experimental plots showed increased bird and insect populations, aiding natural pest control.

Riparian buffers, vegetated strips along rivers mandated by RSPO, prevent erosion and provide wildlife corridors. In Sabah, Malaysia, Musim Mas has restored these zones, boosting fish stocks and water quality while complying with certification. High Conservation Value areas, identified through systematic assessments, protect irreplaceable habitats; for example, HCV orangutan sites in Borneo have preserved populations amid surrounding plantations.

Smallholder initiatives also shine. In Indonesia, agroforestry systems intercropping oil palm with fruit trees or shade crops increase yields by 20 percent while supporting pollinators. These examples demonstrate that conservation enhances resilience against pests, droughts, and market volatility.Explore the tree islands research.

The Pivotal Role of RSPO and Certification Standards

The RSPO, established in 2004, sets principles for sustainable palm oil, including no deforestation, peat protection, and HCV/HCS conservation. Over 86 percent of global palm oil was projected to be deforestation-free certified by 2025, a leap from 19 percent in 2015. Guidelines cover riparian management—maintaining 30-50 meter buffers—and biodiversity baselines via annual audits.

Yet, challenges remain; only a fraction of companies publicly share HCV assessments. Strengthening enforcement, coupled with the study's pathways, could amplify impact. For industry professionals, certification opens premium markets, underscoring the business case for biodiversity.

• Maintain riparian reserves to safeguard waterways
• Conduct HCV assessments before development
• Monitor effluent and greenhouse gases
• Promote zero-deforestation supply chains
