1. Hiking- A Way to Enjoy Nature Irvine Ranch Conservancy

2. In Hiking… • Symbiosis of many plants & fauna, especially the relationship between the yucca plant and the moth and poison oak and mugwort. 各种有趣的动植物共生现象，比如丝兰和蛾子，有毒的橡树和野艾等等。 • Docents: Wonderful volunteers with keen interest in knowing and teaching, showing us some insignificant thing and illuminating it for us. 活动的志愿者们都拥有敏锐的观察力和丰富的相关知识背景，为我们展现了许多奇妙的植物和现象。 • Hi Tech Landfill and issues. 拥有先进技术的垃圾填埋场。 • The resiliency of oak to fire, the value of fire, post fire plants, first one are wildflowers who grow using the char from the fire, and then other plants follow. So fire is seen as a cleaner upper for nature so things stay in balance. 火在自然中被视为清洁工，通过火，植物得以重生，生态得以保持平衡。

3. What did we learn… • Need a staging area for the start which has restrooms and picnic tables. 在活动之前要在一个公共设施齐全的地点集合。 • For a hike there is a head person and the last person. Participants go in between. 在活动中，需要在打头和队尾分别安培一位工作人员保证安全。 • Volunteers need good training and communicate skills. They are the representatives of the organization. 志愿者是组织机构的代表，他们首先需要良好的培训和娴熟的交流技巧。 • We learned to see and pay attention to our own local nature, plants, insects and birds, etc. and know their way of life. 我们要注意观察生活在我们周围的动物、植物和昆虫的生活习性。 • We learned that each plant and kind of life thinks on its own what to do and how to live as best as possible. Possesses reasoning and ability to harmonize through diversity. 动物和植物都拥有自己的思维，他们知道如何在最适合自己的环境中生长，知道如何在多样性的环境中生存。

6. Symbiosis • Yucca丝兰 At night, the female moth who has just eaten male, goes from a yucca that has been pollinated to one that has not. The moth goes from that one up to the other, climb inside the flower, lays an egg. With the egg it carry pollen from one that already has been pollinated. Moth is the only source of pollination of the yucca. When larva is big enough, it will turn up a caterpillar, and it will drop a string down to the ground, climbs down and stay for about a year. When it pops out as a moth, the whole process will start over again. • Moth 蛾子

7. 有趣的共生 • Yucca丝兰 当雌蛾与雄蛾交配后，雌蛾将雄蛾吃掉，之后从已授粉的丝兰上飞到一棵未授粉的丝兰上，在花蕊中产下卵。幼虫破卵后以丝兰的种子为食，在花中吐丝，顺着丝爬到地面，并且在地下生活一年时间，之后破茧化为成虫。飞至另一棵已授粉的丝兰中，继续重复着交配、产卵的生命周期。与此同时，蛾子为丝兰充当的传粉的媒介，帮助丝兰一代一代的生长。而有趣的是，丝兰的寿命一般为5至6年，当一棵丝兰死后，新的丝兰会在已死去的丝兰中再成长，就这样每五年都会循环一次。 • Moth 蛾子

8. The bark of oak is very thick which protect oak from fire. A wild fire will happen every thirty to forty years, which is nature’s way of cleaning area.
