Recovery - MPCD - BIOSINFO

We propose to clean the areas, the sand and the vegetation "In Site" with Biodegradable Chemicals MPCD and Biological Acceptable Products BIOSINFO that are Environmentally Friendly to accelerate the process of Biodegradation. To do that we need heavy machinery to mix the products with the soil and sand and a lot of hand labor "In Site".

Natural Recovery

Marine organisms have varying degrees of natural resilience to changes in their habitats. The natural adaptations of populations of animals and plants to cope with environmental stress, combined with their breeding strategies, provide important mechanisms for coping with the daily and seasonal fluctuations in their habitats and for recovering from predation and other stochastic events.

 Some natural phenomena can be highly destructive. The short-term power of hurricanes and tsunamis can easily be appreciated, as can the damage they cause. The cyclical El Niño phenomenon has major long-term consequences for marine organisms, seabirds and marine mammals throughout the entire Pacific Ocean. Organisms suffer under such onslaughts, but after what is often severe disruption and widespread mortality, the marine populations re-establish themselves over a period of time and this process constitutes natural recovery.

An important reproductive strategy for many marine organisms is the production of vast numbers of eggs and larvae which are released into the plankton and are widely distributed by currents. This mechanism has evolved to take maximum advantage of available space and resources in marine habitats and to deal with e.g. predation. In some cases, only one or two individuals in a million actually survive through to adulthood.

A less common reproductive strategy that is generally restricted to long-lived species that do not reach sexual maturity for many years is to produce relatively few, well-developed, offspring. These species are better adapted to stable habitats and environments and as a result, their populations are likely to take much longer to recover from the pressures of localised mortality e.g. the effects of an oil spill.

Whilst there may be considerable debate over what constitutes recovery, there is a widespread acceptance that natural variability in systems makes getting back to the exact pre-spill condition unlikely, and most current definitions of recovery focus on the re-establishment of a community of plants and animals which are characteristic of the habitat and are functioning normally in terms of biodiversity and productivity.

Restoration

Removal of bulk oil contamination either through natural processes or a well-conducted clean up operation is the first stage of the recovery and restoration of a damaged environment. Dependent on the scale and nature of the spill, for many marine habitats, the clean up operation is all that is necessary to promote natural recovery, and there is little further that can be done to speed up this process.

However, in some cases, especially in circumstances where habitat recovery would otherwise be relatively slow, the clean up operation can be followed by further measures which help restore a habitat structure. An example of such an approach following an oil spill would be to replant an area of salt marsh or mangrove after the bulk oil contamination has been removed. In this way erosion of the area would be minimised and other forms of biological life would be encouraged to return.

While it may be possible to help restore damaged vegetation and physical structures, designing meaningful restoration strategies for animals is a much greater challenge. In some cases it may be warranted to protect a natural breeding population at a nearby non-impacted site, for example by predator control, to provide a reservoir from which re-colonisation of the impacted areas can occur. In reality, the complexity of the marine environment means that there are limits to which ecological damage can be repaired by artificial means. In most cases natural recovery is likely to be relatively rapid and will only rarely be outpaced by restoration measures.

Post-spill Studies

The short-term effects of oil spills on many marine species and communities are well known and predictable, but concerns are often raised about possible longer-term ("sub-lethal") population effects. Extensive research and detailed post-spill studies have shown that many components of the marine environment are highly resilient to short-term adverse changes, including oil spills, and as a result even a major oil spill will rarely cause permanent effects.

However, in some instances, in order to determine the full extent of the damage and the progress of the recovery, it may be necessary to undertake post-spill studies. The costs of post-spill studies may be admissible for compensation under the international conventions (see IOPC Fund Claims Manual) provided they are a direct consequence of a particular spill and are intended to establish the precise nature and extent of environmental damage and habitat recovery. Studies of a general or purely scientific character would not be admissible for compensation.

Studies will not be necessary after all spills and would normally be most appropriate in the case of major incidents where there is evidence of significant environmental damage. Any studies which are considered should be carried out with scientific rigour, objectivity and balance, with the aim of providing reliable and useful information towards assessing pollution damage, reasonable reinstatement measures and habitat recovery. The scale of such studies should be in proportion to the extent of the contamination and the predictable effects.
