RELATED STUDIES ABOUT IMPORTANCE OF BIODIVERSITY

Biodiversity serves as the intricate tapestry of life, weaving together the threads of economic significance and ecological stability. In an era marked by environmental uncertainty, the preservation of diverse biological resources emerges as a cornerstone for sustainable development.

The Importance Of Biome In Shaping Urban Biodiversity

Objective: This review synthesizes current knowledge to argue that the impacts of urbanization on biodiversity differ fundamentally between biomes, with a particular focus on the understudied drylands. It critiques the over-reliance on data and management paradigms from temperate biomes and proposes a framework for understanding biome-specific urban ecology.

Key Findings:

  1. Major Research Bias: Urban biodiversity research is heavily skewed towards temperate biomes. Drylands—the world’s largest terrestrial biome, covering over 40% of land—are drastically underrepresented, especially cities in low-income countries. This limits global understanding and risks inappropriate conservation policies.
  2. The Critical Role of Irrigation: In drylands, supplemental irrigation is the key mechanism altering urban ecology. It can create urban “oases” that are sometimes greener and more biodiverse than surrounding wildlands, but with fundamentally different species compositions dominated by non-native and human-commensal species.
  3. Divergent Biodiversity Patterns:
  • Species Richness: Urban species decline is often less severe in drylands than in temperate zones. Dryland cities can support a higher proportion of the regional species pool.
  • Species Composition: This is where the most critical differences lie. In drylands:
    • Green patches (irrigated, mesic areas) favor non-native species.
    • Gray spaces (built-up areas) and yellowspaces (remnant wildlands or xeriscaped areas) can better support native dryland specialists adapted to heat and sparse vegetation.
  • In contrast, in temperate cities, green spaces are often crucial for supporting native biodiversity.
  1. Socioeconomic and Cultural Mediators: The “luxury effect” (where wealth correlates with biodiversity) is stronger in drylands due to the cost of irrigation. Wealthier neighborhoods can afford lush, exotic landscaping, increasing local diversity but often favoring non-natives. Historic policies (e.g., redlining) and cultural preferences for “greening” also shape urban ecological patterns and environmental injustices in biome-specific ways.
  2. Misleading Focus on “Green”: The global narrative equating “nature” and conservation with “green spaces” is temperate-biased and can be harmful in drylands. It may promote water-intensive landscaping that undermines native ecosystems. The authors advocate for the broader concept of “nature spaces” (including native yellowspaces) as management targets.

Conclusions & Recommendations:

  • Biome-Specific Management is Essential: Policies and management strategies (e.g., urban greening initiatives) cannot be uniformly applied across biomes. What works in temperate cities may be ecologically and socially detrimental in dryland cities.
  • Prioritize Native Dryland Ecosystems: Conservation in dryland cities should focus on protecting and creating yellowspaces (native, xeric habitats) rather than simply increasing generic greenery, to support endemic dryland specialists.
  • Address Knowledge Gaps: Urgent research is needed in low-income dryland cities. Future studies must integrate biome type, socioeconomic factors, and cultural contexts to understand urban biodiversity drivers.
  • Reframe Global Goals: International assessments and sustainability goals (e.g., UN SDGs) must move beyond a temperate-centric, “green”-focused view of urban nature to incorporate biome-specific ecological and social realities.

Broader Implication: Effective urban conservation requires a paradigm shift from a one-size-fits-all approach to context-specific strategies that account for the interactive effects of biome, climate, socioeconomic inequality, and culture.

THE FATE OF BIODIVERSITY FOLLOWING REGULATION AND RESTORATION OF A LOWLAND RIVER OF DANISH AND EUROPEAN IMPORTANCE

Background: The lower Skjern River in Denmark was historically a biodiversity hotspot of national and European importance. In the 1960s, the river was channelized and wetlands were drained for agriculture, leading to severe biodiversity loss. To reverse this, a major restoration project (2000–2002) re-meandered 19 km of the river into a 26 km winding channel, aiming to restore natural hydrology and biodiversity.

Objective: This study evaluates the long-term effects of channelization and subsequent restoration on aquatic biodiversity, focusing on aquatic plants and EPT taxa (Ephemeroptera, Plecoptera, Trichoptera). It compares data from before regulation (pre-1960), after regulation (1976–2000), and after restoration (2003–2012).

Key Findings

  1. Impact of Channelization
  • Taxon richness of aquatic plants and EPT taxa significantly declined after channelization.
  • Losses were most severe for species associated with backwaters (BW) and near-bank zones (NBZ).
  • Backwater habitats were nearly completely eliminated (only 5.8% of the original area remained after restoration).
  1. Response to Restoration
  • Restoration led to a significant increase in taxon richness for both aquatic plants and EPT taxa.
  • Recovery was immediate (within 1 year) and persisted over 10 years.
  • However, richness did not return to pre-channelization levels, especially for backwater-associated species.
  1. Habitat-Specific Recovery
  • Vegetated current zones (VCZ) recovered well, reaching pre-regulation levels.
  • Near-bank zones (NBZ) and backwaters (BW) showed limited recovery.
  • Rare species, particularly those dependent on backwaters, remained largely absent.
  1. Dispersal Limitations
  • Many missing species had distant source populations (up to 300 km away), hindering recolonization.
  • Common species with nearby populations recolonized more successfully.
  • Waterfowl and wind are important dispersal vectors, but stochastic and slow.
  1. Other Factors
  • Weed cutting cessation post-restoration benefited some plant species.
  • Water quality changes had minimal impact on recovery.
  • Invasive species (e.g., Elodea canadensis) did not significantly hinder native recolonization.
  • Climate change effects were negligible during the study period.

Lessons Learned

  • Habitat recreation was insufficient: Only 5.8% of original backwater area was restored.
  • Natural processes are slow: Full channel recovery through erosion and sedimentation may take decades.
  • Stabilization measures (e.g., boulder placement) inhibited natural habitat formation.
  • Long-term monitoring (>10 years) is essential to assess restoration success.

Recommendations

  • Avoid artificial bank stabilization to allow natural hydromorphological processes.
  • Actively create backwaters and islands during restoration.
  • Enhance hydrological connectivity between the river and floodplain.
  • Consider reintroductions of rare species with poor dispersal capacity.
  • Implement long-term monitoring programs to track recovery beyond 10 years.

Conclusion

While restoration of the Skjern River successfully increased biodiversity relative to the channelized state, full recovery to pre-regulation levels was not achieved within 10 years—especially for backwater-associated species. Achieving pre-disturbance biodiversity will require additional active measures, greater habitat recreation, and patience for natural processes to unfold over decades.

Beyond Species Richness: Forest Structure And Edaphic Conditions Have Similar Importance But Different Effects On Multi-Taxon Biodiversity

Key Findings:

This study investigates how forest management impacts biodiversity by disentangling the effects of forest structural changes from underlying soil (edaphic) conditions across seven taxonomic groups in temperate broadleaf forests. Using a paired-stand design (managed vs. unmanaged) in Denmark, the research reveals that:

  1. Taxon-Specific Responses to Management: The overall effect of forest management on alpha diversity (species richness per plot) varies significantly by taxa:
  • Positive for plants and rove beetles.
  • Neutral for ground beetles and mosses.
  • Negative for crane flies, fungi, and lichens.
  1. Equal Importance of Drivers: Both forest structure (e.g., tree size, deadwood, canopy cover) and edaphic conditions (soil properties and moisture) are similarly important in explaining species occurrences and abundances. However, their specific effects differ among taxa.
  2. Individual Species Responses Are Key: Analysis using joint species distribution models (HMSC) showed that individual species’ responses to local conditions are crucial. For example, while ground beetle species richness showed no overall management effect, ~20% of species responded strongly to structural variables, with positive and negative responses canceling each other out at the community level.
  3. Synergies and Trade-offs: Lichens and fungi generally responded positively to mature forest structures and soils with higher carbon/nitrogen, whereas vascular plants responded negatively to these same factors, revealing a trade-off between these taxa.
  4. Limited Direct Management Effect: After accounting for changes in forest structure and soil conditions, the simple management category (managed vs. unmanaged) itself explained little additional variation, indicating that management effects are largely mediated through these altered environmental features.

Implications for Management & Conservation:

  • Move Beyond Simple Categories: Forest management planning and conservation prioritization should move beyond simple “managed vs. unmanaged” classifications and focus on specific, manageable forest attributes like structural complexity and soil moisture.
  • Site Selection is Crucial: Since inherent soil properties (e.g., pH, nutrient content) vary regionally and are less amenable to short-term management, selecting sites with appropriate soil conditions is a key strategy for effective biodiversity conservation.
  • Target Structural Complexity: For taxa that benefit from complex structures (e.g., fungi, lichens), management practices that increase structural heterogeneity, extend rotation periods, and retain deadwood are beneficial.
  • Use Indicator Species: Focusing on individual species’ responses can help identify specific indicator species for certain management intensities or environmental conditions, allowing for more targeted conservation actions.

Conclusion: The balance between manageable forest structure and inherent abiotic soil conditions jointly shapes multi-taxon biodiversity patterns. Effective forest stewardship requires considering both dimensions and the nuanced, species-specific responses within ecological communities to predict biodiversity outcomes and design optimized management and conservation strategies.
