Only examples we have of what a healthy forest in the sierra is supposed to look like. I was invited along with researchers to see it, and heres what i saw. You have to really love the work you are doing if just getting to the office means carrying 40 pounds on your back. I want to know what the forest has to tell me. There are just so many secrets out here. Somebody has to tell their story. I have been working here for almost 20 years and i still dont really have it all figured out and. Reporter the story that brandon and alexis are trying to figure out and share with the rest of us is what happens when naturallyoccurring lightning fires are allowed to burn through these forests. You can go through the last 50 years or more of fires. You will see that one right there, and there is probably one there or there and that is another one, then the rest are all burned down. Reporter since naturallyoccurring lightning fires have been allowed to return to the basin, the flow in the rivers has increased. That is because there is less competition from overcrowded forests. More water in the landscape means there are more meadows. They have documented that the meadows have declined in size and number. More meadows means more wildfires. More wildflowers means more pollinators. That is something researchers have been thrilled to document. On this trip, lex was trying to determine if there is an impact on the bats out here. It does a great job of picking up ultrasonic sounds. Brendan can list the challenges each one of these fires presented almost like he is talking about his kids. 2001, the hoover fire. That really tested the resolve of some of the managers to let that one burn. Reporter as for lex, she has her reasons for spending more time in the field here than most researchers. I am proud of the forest we have here but i also recognize that we have a lot of work to do, so i want to be able to be an agent of change. Reporter both will tell you they are only able to do this work because of the giants at berkeley before them. In 1970 when this picture was taken they were ridiculed for being reckless. There is more risk than reward. At least if you are thinking about it from a career standpoint. But here we are benefiting from the science side of that and able to tell a really neat story about fire in this natural landscape. Reporter about those 16 miles, if anybody wants to see how sierra forests can thrive over the next 50 years, come to the basin where you can see it for yourself today. I really like it here. When i think of textbook, healthy fires, this is what it looks like to me. Reporter because this is such a unique patch of forest we have got 50 years of documentation to show the results. This little key shows you what the composition of the forest was in 1969 before they started letting the lightning fires go. I will play this forward decade by decade. They have put together this series of maps so that we can visualize the transformation in these forests over the past 50 years. What you see on this one is a complex of diversity. It is not just constant overgrown young and crowded pine trees. Instead what you have are a mix of meadows and shrub land. What forests used to be in the sierra before we started unknowingly inking we were doing what was right by removing all the fires. Now as a consequence, fires will happen one way or the other. When forests look like that, you get mega fires. If they look like this it is a natural defense these forests have evolved for thousands of years without our help. That is how we have gotten into the problems we have gotten. It was such a unique experience, guys, to be along with these. It is a story of yosemite but also a story about our backyard. These are researchers here at uc berkeley in the 70s. People thought they were nuts some still do yeah, some still do, but 50 years later they are proven right. Those healthy fires are so important, but when you see one just from a distance, you cannot help but hold your breath if that is going to stay controlled, because that is the risk with these healthy fires. I could not help but notice that you took a little drink from the stream there. Good for you, nature boy that is one thing most people comment on because they know you have to filter the water. I am holding a filter in the other hand and i did filter that water. Still, that has to be the cleanest water you have had in a long time you but it was but you have always got to filter the water when you are up there. It was a nice day in the office, but you actually hiked we ended up going out eight and then you have to go back out the next day. It was totally worth it. For that part of the park, the basin, it is kind of just east of glacier point. When you go to glacier point, that is all the basin. Beautiful. The flowers alone were spectacular. Great story. In efforts to save salmon, the Sacramento Water Forum is building a new series of habitat restorations along the river. Construction begins this week along ancell hoffman park.

Once the project is complete there will be no visible changes to the parkway. A federal court will allow Abortion Pill mifepristone to stay on the market but with restrictions.

We are still actively investigating the incident while simultaneously praying and caring for the wounded officer and her family as she is still in the hospital and in stable but critical condition.

Potentially dangerous weather coming our way, brian we have the sub tropical moisture coming up and that has triggered lightning over not only the sierra but also parts of the bay area. So yeah. It does make you do more than raise an eyebrow, especially since the lightning triggered the fire around klamath, which has burned 4000 acres. You can see the buildups east of downtown San Francisco and out towards the big thunder bumpers which are producing rain in parts of the bay area. You can see it right there with the darkening sky in the distance. You can see low clouds hanging around the coast, and as a result we are looking for things to cool down a little bit, but that is not until friday. Tomorrow low pressure is hanging off shore. With the low hanging around we continue the southerly flow. Right now here is what we are expecting in the headlines. Areas of fog tonight will be cooling to normal. Convective clouds remain which means we could get a popup shower or two, especially tonight. The weekend looks dry and mild, but monday and tuesday is a big question mark. Monday and tuesday we could get showers in the bay area. Right now you can see the little cell that is east of san jose moving into the foothills, but look at the southerly flow. All of those clouds coming from south to north. As time goes on, especially as we get into friday, look at the low clouds that are blossoming into the central part of the sacramento valley. That is the biggest sign that things will cool down. On friday , inland it was in the midtoupper 90s. The good news is by friday we are only in the 80s in the east bay, so there is cooler weather on the way. You can see that by concord tomorrow. And look at all the numbers tumble on friday. This is all causing allergens to pile up, especially the grass and these pods that are at medium level. If you notice yourself especially sniffly, now you know why. Look at the layer of clouds against the Golden Gate Bridge with the south tower just barely popping out there. So it is going to be cool along the coast. Low temperatures tonight are in the low to mid 60s. High temperatures torr are in the mid80s, so a little bit cooler there, little bit cooler in the east bay. Instead of upper 90s, low to mid 90s and that is a step in the right direction. A lot of sunshine mixed with high clouds in the north bay but still plenty warm. Ukiah, 101, santa rosa, 83. Increasing clouds on friday could be a popup shower. Sunday and monday we cloud up. The east bay on the coast ill get cloudy on monday and the result is that we could get a few showers coming in early next week.

The organization looking to make a difference one penguin at a time. Reporter this day is cause for celebration as these penguins waddle back into the wild off the coast of argentina. Months ago they entered a Rehabilitation Center in pretty bad shape. They were malnourished, dehydrated, hypothermic and parasitic area and some were even exposed to oil and had eaten plastic, said sergio rodriguez, a biologist at the center. Veterinarians talk penguins under their wing, cleaning and feeding them while restoring them to health, but they swim off into an uncertain world. Climate change threatens to destroy their habitat while overfishing risks starving the flightless birds. Scientists warn that all of this could lead to their extinction. Of all the known birds, penguins are the slowest to adapt and evolve. Centers like this can only do so much. All these afflictions are directly or indirectly caused by humans.
