Tip: For joints 1/8 inch to Â½ inch, use sanded grout. For joints up to 1/8 inch, use non-sanded grout. â¢ Before grouting, remove all of your tile spacers. Again, leaving the spacers in place and grouting over them will compromise the integrity of the grout.
The assessment, conducted by the Primate Specialist Group of the International Union for the Conservation of Nature (IUCN), concludes that 23 lemurs qualify as Critically Endangered - the highest class of threat. Fifty-two are in the Endangered classification, and a further 19 Vulnerable to extinction.
A Critically Endangered listing can mean the population numbers less than 50 mature adults or that it has shrunk by 80% over 10 years, for example. The previous lemur assessment, published in 2008, put eight species in the Critically Endangered class. Eighteen were Endangered, and 14 Vulnerable.
