At noon, everyone pauses for an hour to eat, and then moves forward. In addition to the surprise that the cave has brought to people, these expeditions have not yet found themselves interested.

Turning around an inlet, everyone came to a valley with a negative back. The two botanists present immediately widened their eyes, and only after half a sound did they exclaim: "It's Alder, this valley is actually full of Alder." ”

Other experts who are not studying plants are also a little dumbfounded, they didn't expect that there would be so many alders, this is a first-class endangered plant! There are so many here that it hurts, not like it's endangered!

Alder is the only woody fern in existence, which is extremely precious and can be called a national treasure, and is listed as an endangered plant under first-class protection by many countries. It belongs to the more primitive vascular plants, the phylum Ferns, and the family A. spinulaceae. Alders are descendants of an ancient fern family that can be made into crafts and traditional Chinese medicine.

"Look at them, this thing seems to be very precious!" Zhou Furong secretly said to Chen Wu, Chu Jiaqiang and others. He also often sees this kind of expression, and some antique predecessors see a rare treasure is this virtue.

"National treasure-level plants, do you say they are precious?" A Ph.D. student rolled his eyes.

"A national treasure? It's not like that! There are not 10,000 or thousands of them here, right? When did the flood of national treasures reach this point? Chen Wu was also glaring, obviously thinking that this "national treasure" was a bit of a wasted name.

Those experts were choked speechless by Chen Wu's words one by one, and they were right, the facts were in front of them, these alders appeared in a pile, and the people who couldn't do it really didn't believe that they were first-class protected plants.

Alder is a semi-negative tree species that prefers warm and humid climates, and prefers to grow in alluvial soil or under forests near valley streams. About 180 million years ago, alder was the most abundant plant on Earth, along with dinosaurs. Two major symbols of the "reptile" era. However, after a long period of geological changes, most of the earth's alders have been killed, and only a few can be traced in places called "shelters".

Minnan Overseas Chinese Township South. Next to Lezhu Village in Jingxian County, there is a subtropical rainforest. It is the smallest forest ecosystem nature reserve in China. It is "the world's rare multi-level monsoon subtropical primeval rainforest". There is the world's rarest plant, the alder. Alder spinula ranks first among the eight protected plants in China. New Zealand is one of the producing areas of alder, and it is also the national flower of New Zealand, which is protected by people.

"Such a large piece of alders. It is the first discovery in China, and it is not an exaggeration to say that it is the world's first alder forest. The plant expert surnamed Hong quickened his pace, his eyes glowing, as if he saw a pervert seeing a group of beauties, which made Chu Jiaqiang and the others creepy.

No wonder they get excited. It is not easy for these alder trees to grow, let alone grow in patches?

The sporophyte of this species grows slowly, the reproductive cycle is long, and the spore germination and gametophyte development as well as the mating of gametes require a mild and moist environment. Due to the shrinking of forest vegetation cover, the habitats in the existing distribution area tend to be dry. As a result, the gametophyte reproductive link is seriously hindered. There are few young plants under the forest. In addition, the stem can be used for medicinal purposes and for the cultivation of epiphytic orchids, which are often cut down by people, and the plants are decreasing day by day, some distribution points have disappeared, and the lower limit of vertical distribution has also increased with the shrinkage of vegetation. Today, this precious ancient species has reached the point of extinction.

"I'm afraid I'll have to give up time to this alder forest today." Fu Lao said with a smile.

He is well aware of the character of these people. Seeing this alder forest, don't really want to leave today. The next step is to investigate the entire alder forest. The number of them, the condition of their growth. size, and growing environment (sunlight, moisture, soil...... And so on. Even taking some specimens and leaving is something to do in the field. The last step is to write a report and write the situation in as much detail as possible.

"Lao Hong, you first use the camera to take pictures in all directions, and I'll walk through it roughly first, and figure out the area and the number of alders." Expert Wu shouted happily.

"Don't worry, I know how to do it." The two worked together seamlessly.

Li Quan frowned and said, "You didn't find this piece of alder last time?" ”

Those people suddenly blushed a little, last time they didn't take this road, they walked on Yangmian Mountain, and they didn't find it on this side. I didn't expect that there was only a mountain away from this national treasure plant last time, if it wasn't for Chu Jiaqiang to lead the way this time, this alder forest would have to continue to be hidden.

"The last time we walked over there, this mountain was in the way, and we definitely couldn't find it. These roads are too difficult to walk, and few people will be idle and have nothing to do, and run into these deep mountains and old forests to be savages. The villager spoke. He didn't walk this road, it was the road over there, and he also walked it twice with his father when he was a child.

"Everyone, help! Otherwise, I may have to give my time here tomorrow. Fu Lao said to everyone.

Those present, except for Chu Jiaqiang, Zhou Furong, Li Quan and Chen Wu, are all engaged in endangered biological research. Although one is an animal and the other is a plant, sometimes, the direction of the investigation is the same, and everything is the same, it is nothing more than collecting some reliable data, which everyone will.

Chu Jiaqiang immediately drilled inside, and seeing that there was no one, he secretly used the power of the mountain and river map to move a part of the alder to the mountain and river map for planting. Although there are many alders here, it is difficult to say whether they will become extinct in the future.

The wonderful use of the mountain and river map was only recently discovered by Chu Jiaqiang, the plant can be taken away with his own mind, but there will be no potholes on the ground, no clues will be revealed, and no one will suspect that there was once a plant growing here.

The others are busy, and Chen Wu and the others will not join in the fun, just to take a break. The three of them took off their shoes and sat down on the rocks by the stream to soak their feet, which was a great pleasure.

And Fu Lao and the others don't expect them to help, thank God for not getting in the way. Seeing that they did not make trouble, they breathed a sigh of relief.

Chu Jiaqiang soon received nearly 100 alders into the mountain and river map, and set aside a place to transfer these alders to grow. With the spiritual water, he was not afraid that these alders would not grow well, or even be unable to grow. Coupled with the time difference in the mountains and rivers map, he believes that in a few years, the alders in it will be calculated in tens of thousands.

With so many people, it took three hours to explore the entire alder clearly, and the two plant experts were satisfied with it. They began to look forward to this expedition. Not to mention anything else, just this piece of alders is enough to make their trip worthwhile.

"There's still some time, let's keep going!" Fu Shenglin said.

"The first three kilometers are enough to stay overnight, so we try to get there as fast as we can." Chu Jiaqiang revealed, in fact, he didn't know what was going on there.
