Ihirwe with Caretaker Innocent

RUHENGERI, RWANDA — Approaching the age of 2, orphan Ihirwe is quite a rambunctious little gorilla and grows bolder by the day. People passing by the MGVP’s gorilla quarantine facility in Kinigi even at a distance might glimpse Ihirwe scrambling in tree branches high above the ground. It’s amazing to think that a baby could be so brave and agile! But like any infant, Ihirwe sometimes gets into trouble on her adventures. Several days ago Ihirwe fell out of a tree and nearly knocked her two front teeth out. Fortunately the Gorilla Doctors are always ready and nearby to take care of medical problems affecting mountain gorilla orphans. Below is Dr. Noel’s report about Ihirwe’s accident.

On January 20, caretakers reported that Ihirwe was climbing a tree in the enclosure when she suddenly fell from a height of about 3 meters. She landed on her face and appeared to have hurt her mouth. There was a small amount of bleeding for approximately two minutes.

The caretakers called the MGVP office and Dr. Dawn and I drove to Kinigi to check on Ihirwe. When we arrived, Ihirwe appeared frightened but otherwise bright, alert and responsive. No signs of neurological deficits were observed.  She even drank a bottle of milk shortly after the fall.

Ouch!

Her mouth looked painful, however, and she was moving her tongue frequently. Two incisors (left mandibular I1 and I2) had been knocked forward, but not out, and I observed a mild hemorrhage along the associated gingival laceration. Her jaw appeared stable with no sign of a fracture.

We decided to treat her with pain medicine and an antibiotic to prevent infection. Later in the day the caretakers reported that she was eating normally. I visited her again the next day and she looked well. She did not show any signs of pain while eating. I looked at her mouth and her two incisors had loosened even more and flipped forward. The teeth are still attached to the gingival, but likely they will fall out on their own in time. These are baby teeth, so the early loss of the incisors will not impact her future.

The caretakers will report back to me if they notice any signs of trouble, but I think Ihirwe is on the mend.

Silverback Kabirizi's role as king of Virunga threatened

This Blog was written by Dr. Eddy from Virunga National Park, DRC.

RUHENGERI, RWANDA — On the morning January 20, I left the Bukima patrol post with a group of trackers to find Kabirizi group. Along the way we encountered the night nest of the silverback Mukunda, who still stays by himself in the forest. About 30 minutes later we met a wild or unhabituated gorilla group, a very rare occurrence. The group was quiet initially but later they moved away, with the silverbacks charging and screaming at us. We know from the 2010 census that there are several large unhabituated groups in Viurnga.

Almost three and a half hours after starting our trek, we found Kabirizi group. The weather was sunny and almost all of the gorillas were sitting under shade in the bushes which made our observation quite long and difficult.  We counted 33 individuals, including Kabirizi himself.

I realized that Kabirizi was quieter than usual. He was not charging, hiding or running, and he was eating out in the open with his family members. Normally Kabirizi does not like being observed by people, and stays hidden in the vegetation, keeping the group’s babies close to him for protection.  I noticed that Kabirizi has many healing wounds on his left shoulder and thigh and a large cut (about 7 cm) on his right heel which was healing but not allowing him to walk properly. He was limping on the right side and using his left leg a lot while walking.

Kabirizi is missing his canines.

Some time ago, Kabirizi lost his upper and lower canine teeth during a fight with another gorilla. I think that his lack of canines, his defensive weapons, is one of the reasons why it is easy for the other silverbacks in the group to take advantage of him in fights. The younger silverback Bagheni  have been fighting with Kabirizi on a regular basis now, and Kabirizi most often loses the battles. Another young silverback in the group, Mugeni, is also starting to challenge Kabirizi.

While the other gorillas in the group appear healthy, Kabirizi is declining due to a combination of aging and frequent fighting with the other silverbacks. It will be very interesting to see how the dynamics in the family change this year.

Research Notes:  Kabirizi has been one of the most successful silverbacks in Virunga National Park, having sired dozens of babies during his 14-year reign as leader of Kabirizi group. Famous for his aggressiveness towards people and other gorillas, Kabirizi has killed a number of  male gorillas while defending his family.

Improved health monitoring tool benefits veterinarians and gorillas

By Molly Feltner

RUHENGERI, RWANDA — How do the Gorilla Doctors keep mountain gorillas healthy? The first step, and the foundation of our gorilla healthcare program, is gorilla health monitoring — visually observing the members of  gorilla groups on a regular basis to check for signs of illness or injury. MGVP is only able to monitor and treat gorillas in habituated groups — groups that have grown accustomed to the presence of humans after a long process of being gradually approached by people. Luckily for the Gorilla Doctors, most of our patients are easy to find and comfortable being observed at close range. About 73 percent of mountain gorillas in the Virunga Massif are habituated while about 50 percent are habituated in Bwindi Impenetrable National Park.

The Gorilla Doctors visit every habituated mountain gorilla group once per month to perform a thorough visual health check. During a routine health check, the veterinarian tries to make visual contact with each member of the gorilla group in order to check a variety of health parameters:

  • Body condition: Does the animal look well fed and healthy?
  • Activity: Is the animal alert? Does it show any signs of weakness or lethargy?
  • Respiration: Is the animal breathing well? Is it coughing or sneezing?
  • Skin and Hair: Does the animal have any visible wounds, skin lesions or unusual growths? Is its coat dull, discolored or falling out?
  • Head/Face Discharge: Does the animal have any visible signs of illness on its head or face such as a runny nose or eye discharge?
  • Stool: Does the animal’s stool appear normal?

Careful notes are taken for each animal. When a gorilla is found to be suffering from human-induced or life-threatening injury or illness, the Gorilla Doctors, in collaboration with national park authorities, make plans to medically intervene in order to save the animal.

In addition to the veterinarians’ monthly checks, MGVP relies heavily on the observations of the trackers working for the national parks and organizations like Karisoke Research Center. The trackers see the gorillas every day and are trained by the Gorilla Doctors to look for any behavioral changes and other signs that could indicate illness and injury. Concerns are reported back to the Gorilla Doctors who follow up to perform their own visual health checks.

To keep track of the health histories of the different gorillas the Gorilla Doctors have recorded their health check data in a system called IMPACT (Internet Management Program to Assist Conservation Technologies) for the past 6 years. IMPACT was originally designed by programmer Rich Minus and was recently revamped by Medical Decision Logic.

Thanks to the improved system, we’re now training trackers to record their observations in IMPACT rather than simply reporting to MGVP when a problem is noted. By keeping an organized record of the daily observations of the trackers, the Gorilla Doctors and other researchers will have a much more in-depth understanding of the health trends in the population as well as a clearer picture of the overall health of individual gorillas. A group of 40 trackers from Volcanoes National Park and Karisoke Research were trained to use the IMPACT system this January. Trackers in Uganda and DR Congo will also receive training in the upcoming months.

Top ten ways to protect mountain gorillas

By Molly Feltner

RUHENGERI, RWANDA — The recent popular YouTube video showing a tourist being touched by wild mountain gorillas has captivated more than a million viewers and will likely inspire many travelers to book a trip to visit mountain gorillas themselves.

While the desire to connect intimately with one of our closest relatives is an innate reaction, such close contact with this endangered species is not in the best interest of their conservation. Disease transmission due to contact with humans is a very real problem for mountain gorillas, some of whom have become ill as a result of their proximity to humans. That said, tourism and the work of scientists, researchers and other experts with gorillas are absolutely vital to the species’ survival.

For those of you looking to make a positive impact on mountain gorilla conservation, the Mountain Gorilla Veterinary Project would like to suggest 10 ways in which you can help:

1. Trek to see the mountain gorillas in Rwanda, DR Congo or Uganda.

Without gorilla tourism, mountain gorillas might have gone extinct. The regions where mountain gorillas live are home to the densest human populations in Africa. Most of the people living in these areas are farmers, so land is critical to their livelihoods. However, the governments of Rwanda, Uganda and DR Congo have kept the gorilla’s volcano habitat off-limits to agriculture  in order to protect the gorillas, largely because the revenue gained through tourism outweighs the value of forested slopes for other purposes. Gorilla trekking permits are pricey ($400 in DR Congo and $500 in Rwanda and Uganda), but by purchasing permits, you’re not only buying a once-in-a-lifetime encounter with this charismatic species, you’re providing the economic incentive for the gorillas’ protection. Visit the tourism websites for gorilla trekking RwandaDR Congo and Uganda to learn more.

2. Do not trek to see gorillas if you are sick.

Due to the genetic similarity between humans and mountain gorillas, gorillas are susceptible to many of the same infectious diseases that affect people. Mountain gorillas are also immunologically naïve, meaning they are particularly susceptible to human diseases because of their historic isolation from people. Research conducted by the Gorilla Doctors and other scientists has proven that mountain gorillas have died as a result of infections that originated in people. Infectious disease, after trauma, is the leading cause of death in mountain gorillas, accounting for 20 percent of acute mortality. The most common infection is respiratory disease, which can range from mild colds to severe pneumonia. To protect gorillas from such infections, the national park authorities ask that anyone feeling sick or running a fever to not trek to the gorillas.

3. Stay at least 7 meters away from the gorillas.

In order to reduce the risk of disease transmission and to avoid changing or disturbing the gorillas’ natural behavior, the Gorilla Doctors have worked with national park authorities to establish the rule of staying 7 meters (21 feet) or more from the gorillas at all times. The gorillas themselves, especially youngsters, don’t know the rules and may approach humans, but tourists should make the effort to back away and avoid touching the animal if possible. The 7-meter rule should be observed at all times, even when gorillas leave the national park and venture on to property owned by tourist lodges and camps.

4. Donate to conservation organizations working to protect mountain gorillas.

One of the most effective ways to help mountain gorillas is to donate money to organizations working on the ground to conserve the species. Numerous organizations including MGVP have spent decades finding effective methods for protecting mountain gorillas, and most rely on grants and donations to fund their work.

When donating your money to support any cause, it’s important to evaluate the organization you’re considering supporting to determine how successful the group is in carrying out its mission. You should find the answers to questions like,  “What methods does the organization use to accomplish its stated goals?” and “Does the organization have any data or statistics to show that its methods are having an impact?” An organization’s website and annual reports should provide this information, or you can always send an inquiry to their public information or development officer.

MGVP is proud to be the only organization providing direct life-saving medical care to mountain gorillas in the wild. Research has shown that the work of the Gorilla Doctors and the anti-poaching efforts of the park rangers and trackers we work with is responsible for up to 40 percent of the growth of the human-habituated mountain gorilla population in the Virunga Massif over the last 10 years. Donations can be made through the Gorilla Doctors website.

5. When visiting the region, do other activities in the parks in addition to gorilla trekking.

The vast majority of tourists who visit the national parks where gorillas live spend a day or two trekking gorillas and then leave. However, all of the gorilla parks offer other amazing wilderness experiences. As with gorilla trekking, the revenue earned through these activities further incentivizes the governments and local people to protect mountain gorilla habitat. You can climb the active Nyiragongo volcano in DR Congo, home to the world’s largest lava lake, or can climb extinct volcanoes in Rwanda and Uganda, such as the snow-covered Mt. Karismibi or the fluted peaks of Mt. Sabyinyo. Both Rwanda and Uganda offer treks to see golden monkeys (another highly endangered primate), and in Rwanda you may also visit the gravesite and former research station of Dian Fossey. Ask your tour provider about the options available.

6. Support local businesses and community projects around the national parks.

As much effort as the governments and conservation organizations put into protecting the gorillas, the support of the local people surrounding the parks is vital to ensure the preservation of gorilla habitat and the conservation of mountain gorillas. The more that local people share in tourism revenue and benefit from non-profit and community efforts in the area, the more likely they are to want to protect the mountain gorillas. Tourists can help by frequenting local restaurants, shops and other businesses, or by making contributions to community projects around the park. For instance, tourists can pay to visit the Iby’Iwacu Cultural Village near Volcanoes National Park, Rwanda, which employs former poachers as cultural interpreters and performers.

7. Don’t buy products made with wild animal parts.

While mountain gorillas are very rarely targeted by poachers, other animals living in the national parks where gorillas live are actively hunted. Poachers mostly set snares to catch small antelopes to bring home to their families for food, but occasionally larger animals such as buffalo or elephants may be targeted. Gorillas often get caught in poachers’ snares set for other animals. Furthermore, poachers’ very presence in the forest disturbs the environment and increases the risk of zoonotic disease transmission. While the main purpose of poaching is to obtain bush meat, wild animal skins, bones and ivory may be used in crafts and other items sold to tourists. If you have any doubt about a product’s origins, don’t buy it. And certainly, in the rare instance you may see or hear of someone selling a live wild animal, report it to the national park authorities.

8 . Trek with a tour provider that donates a portion of the trip cost towards conservation efforts.

When researching tour packages to see gorillas, consider booking with a provider that directs a portion of their profits to support conservation projects. For example, Terra Incognita Ecotours, which offers 8-day Rwanda tours including a visit with the Gorilla Doctors, donates a portion of the trip cost to MGVP. In DR Congo, you can book packages including permits, transport, and accommodations directly through Virunga National Park, which puts profits right back into the park itself.

9. Organize a fundraiser.

Can’t afford to make a significant personal donation or travel to Africa? Organize or participate in a fundraiser to help raise money for mountain gorilla conservation. In the past, schools have raised money for MGVP through bake sales and fun runs. Travelers and volunteers visiting gorillas in Rwanda have sold gorilla t-shirts to raise money to pay for their trips and make a donation to MGVP. One of biggest our fans even raised $30,000 in donations and pledges by walking 228 miles from Seattle to Portland, Oregon!

10. Spread the word about mountain gorilla conservation.

Anyone can make a difference for the gorillas by telling their friends, family, and colleagues about the mountain gorillas and the efforts being made to save them. Remember that even though mountain gorillas are critically endangered, their story is a positive one! Mountain gorillas are the only subspecies of non-human great ape growing in number. Fewer than 250 animals were counted in the mid-80s when Dian Fossey was researching the gorillas, but today the population numbers are nearly 800 animals. This species has a fighting chance for survival if we continue to work to address conservation challenges.
