Conservation status and the IUCN Red List


To monitor the status of how likely an animal is to become extinct, there are people who work together to record the population levels of species and compare it to previous records to see if the population has increased or reduced. Based on the threshold of which the population number has reached, the species moves onto different levels of conservation status.
The group that works with conservation status is called the International Union for Conservation of Nature (IUCN) Species Programme. The program works with IUCN Species Survival Commission (SSC). They have been assessing conversation statuses of species for the past 50 years to highlight any organisms threatened with extinction and work to prevent it. The IUCN Red List of Threatened Species is one of the most comprehensive, objected global approach for evaluating the conservation statuses of plant and animal species. To date, there have been more than 76,000 species that has been assessed for the Red List. 

The conservation status is as follows (from most to least dangerous):
  • Extinct (EX)
  • Extinct in the wild (EW)
  • Critically endangered (CR)
  • Endangered (EN)
  • Vulnerable (VU)
  • Near threatened (NT)
  • Conservation dependant (CD) 
  • Least concern (LC)
  • Data deficient (DD)
  • Not evaluated (NE)
Conservation statuses are calculated by breeding rates, increase/decrease of populace, known threats and the number of population. 

 In 2017, they assessed several species to check their conservation status. Some examples of species that have became endangered are Miyako Grass Lizard, Bounded Ground Geko, Irrawaddy Dolphin and Gold Spotted Marsopial Frog. 2 species became extinct in 2017 (Christmas Island pipstrelle and Christmas Island Whiptail-skink). People do not know about this unless they look at the red list, so I will base these animals in my work so people know about it.

Fine Art Photography - Editing Photos

Image
When I took my photos, I decided to edit them in Photoshop. I decided I wanted to edit them rather than keep them as they were because adding colour onto photographs that already contain colour wouldn't give me the contrast I wanted in my photographs. I also wanted my pieces to focus on only one colour that would represent the emotion associated with the music that it gives to the subject when they listen to it. The colour would also represent the emotion that they feel if the song reminds them of a certain memory.  To begin, I wanted to change the saturation of the photograph by -100, making it transform from colour to grey scale. I feel adding the grey scale will allow my piece to be in the background and not focused on when I add the colour onto the piece. It also increases the contrast and allows the person to focus on the particular colour, meaning that the connotation surrounding that colour would be obvious to the person viewing the piece.  While looking back...

Final Piece Preparation - Mock Final Piece

Image
To prepare for my final piece, I have created what I feel is a sample of the final piece idea I had in mind.  With this mock final piece, I have experimented with composition of the photos as well as the background of which I feel will make the photographs stand out the most as a piece.  For my photographs, I felt the best composition was similar to a sound wave. This is because sound waves are the focal point for my piece, being what my entire project is based on for the lines and colours. To further bring sound waves into my piece, I have made the photographs themselves as a large sound wave that further emphasises the importance of sound waves, and how they songs effect everyone's thoughts, memories and emotions in life.   I have made the photographs different sizes as I feel it helps emphasise certain photographs. As well as this, it makes the piece seem much less flat and repetitive, as it makes different photographs all unique, with different tech...
