Interaction between Nitrogen, Phosphorus, and Invasive Alien Plants

Plant invasion is significantly affected by environmental factors in the recipient habitats and affects the stability and sustainable development of society. The invasiveness of alien plants may be increased by anthropogenic-mediated disturbances, such as fluctuations in nutrients caused by excessive emissions of nitrogen (N) and phosphorus (P). To improve our understanding of the interactions between N and P fluctuations and invasive alien plants, the current report focuses on the biogeochemical behavior of N and P among invasive alien plants, native plants, and the soil within the plant–soil ecosystem. Our research, together with a synthesis of the literature, shows that fluctuations in N and P resources provide more opportunities and competitiveness for plant invasion. At the same time, the biogeochemical cycles of N and P are promoted because of their efficient and increased utilization and rate of release by invasive alien plants. However, there is no consensus on whether the N and P compositions of invasive species are different from those of the natives in their habitat. Quantitative studies that compare N and P contents in plant, litter, and soil between native plant communities and invaded communities on a global scale are an indispensable area of research focus for the future.

Invasive Alien Plants

Changes in the climate have worsen the problems caused by weeds and invasive alien plants (IAPs) in agro-ecosystems at global scale resulting from their changes in the range and population densities. Over the past six decades, Sri Lanka has experienced a slow but steady increase in annual environmental temperature by 0.01–0.03°C. Increasing extreme events of rainfall, wetter wet seasons, and drier dry seasons are some of the characteristic features of the changes in the climate observed in Sri Lanka over the years. The Ministry of Environment (MOE) in Sri Lanka has established a National Invasive Species Specialist Group (NISSG) in 2012 and adopted the National Policy on Invasive Alien Species (IAS) in Sri Lanka, Strategies and Action Plan in 2016. Further, the MOE has developed and adopted protocols to assess the risk of IAS at pre- and post-entry level to the country while incorporating climate change concerns. Periodic risk assessments have being carried out to prioritize actions against IAS in Sri Lanka. The Ministry of Agriculture as adopted a National Weed Strategy (NWS) and has identified the Weeds of National Significance (WONS) under different priority crops. A study done in 2014 has clearly shown that weed control costs in agricultural lands in several district of Sri Lanka were nearly doubled during the years that experienced El Niño Southern Oscillation (ENSO). Further, studies have clearly indicated that IAPs also survive, expand and impact the continuously disturbed environments in agro-ecosystems. Panicum trichocladum, a species listed as a potential invasive based on the risk assessment done in 2016, has shown an increase in its population density and distribution in Sri Lanka during the last 2–3 years. However, weeds and IAPs in agro-ecosystems have drawn less attention of policy makers, scientists, and practitioners in relation to impact of climate change in island ecosystems. This paper focuses on the scientific evidence reported in agro-ecosystems in Sri Lanka on climate-related impacts on agriculturally important weeds and IAPs, and the efforts made to manage their introduction and spread across the country.

Invasive Alien Plant

Abstract Riparian invasive alien plants are known to compete with native plant species for water, space, daylight, and different other resources by decreasing structural diversity of native vegetation and subsequently changing the functioning of the ecosystem. The aim of this study was to investigate the rate of native plant species recolonization after the eradication of A. decurrens. The investigation was done in the Waterberg District Municipality, Limpopo Province in a farm, which is highly infested with A. decurrens. Twenty-four permanent plots of 10 m x 10 m were constructed and the A. decurrens individuals in the plots were removed and the area was monitored for a period of 2 years. The size of quadrats was based on the size and distribution of the invasive alien plants which develop in an aggregated form and have exceptionally small canopies.

Soil Feedback

Plant invasion is a key element defining the community structure and dynamics and has become a major concern for the invasive plants to control the restoration of ecosystem diversity. In the same line of thought, soil microorganisms are also considered as a significant parameter of evolution and invasive plants' success. The variations usually overserved in the composition and structure of the soil microorganisms and the consequences of plant invasion. Therefore, understanding the concept of plant invasion and soil microorganism impact plant competition and plant-soil feedback would be a very important step forward in invasive plant control and ecosystem restoration. This review aims to provide a conceptual explanation of plant invasion, the role of soil microorganisms on plant growth and its effects on the native plant-soil feedback and also to demonstrate the importance of understanding the integrative soil microorganism impact on the competition between native and invasive plants along with its effects on plant-soil feedback.

The status of native floral diversity in Mt. Manunggal, Cebu Island, the Philippines in relation to environmental factors and alien plant invasion has not been recorded and published. To assess factors influencing native plant communities in Mt. Manunggal, a vegetation survey of native and alien plants, as well as selected environmental variables at two sites (Site 1- invaded plot; Site 2- adjacent uninvaded plot) were measured, and anthropogenic disturbances observed using a t-test, regression analysis, and Pearson correlation. For each site, selected environmental parameters, as well as native and alien plant abundance and diversity, were determined last October-November, 2016. There was also a characterization of sites with respect to anthropogenic disturbances. Altitude (t= -14.11, p=0.000), soil temperature (t=2.68, p=0.014), and light intensity (t = -2.61; p=0.016) significantly differed between study sites due to the complex topography and geology of Mt. Manunggal, the variation in floral cover, and degree of anthropogenic activities. Among all environmental factors at both sites, altitude was highly positively correlated to alien plant abundance (r=0.709;p=0.000) at Site 1 while native plant abundance at Site 2 was negatively correlated with soil pH (r=-0.579;p=0.003).There was an apparent domination of alien plants in terms of species richness and abundance at both sites and this could have significantly affected native plant abundance. The strong correlation of environmental parameters to alien plant invasion could favor the continued dominance of alien plant species, resulting in a further decrease of native species.

Plant Soil

Land resources are finite, comprised with biophysical complexities (biodiversity, soil, and water resources), vital in sustenance of life. However, multiple anthropogenic disturbances transmogrified the global landscapes with spread of invasive alien plants (IAPs), and perturbed the land-biophysical components, thereby triggering the ecosystem degradation. Nevertheless, the interrelationship of IAPs with land degradation and sustainable restoration is not well established. Furthermore, the restoration challenges of IAPs driven land degradation is also exacerbated under the event of climate change. In this review, the adverse impacts of IAPs on biophysical components of land resources are discussed to explicitly assess the drivers of ecosystem degradation. Restoration efforts of degraded lands should be therefore targeted to revitalize the associated biophysical complexities. Further, the explicit study on the effects of IAPs on plant-soil and plant-soil microbe interactions need to be at the heart of sustainable land or ecosystem restoration strategies. Several studies refused the blanket condemnation of IAPs in ecosystem restoration, ascribed to co-benefits (bioenergy, phytoremediation, biopolymers, and ethnomedicines), inextricably linked with the coverage of financial incentives. Nevertheless, the use of IAPs in ecological restoration needs pragmatic evaluation in terms of long-term ecosystem effects. To this end, the incorporation of ‘hybrid technology’, integrating scientific information with traditional ecological knowledge (TEK), can be the founding principle of sustainable ecosystem restoration and rural livelihood. Importantly, holistic approach in restoration of degraded lands in concert with ‘circular economy’ can remarkably influence in achieving the target of UN Sustainable Development Goals (UN-SDGs) and UN Decade on Ecosystem Restoration (UN-DER) (2021-30).
