Here are several options for a description of the WordPress post tag “特有種” (Tèyǒu zhǒng, which translates to “endemic species” in Traditional Chinese), ranging from concise to more detailed, along with the rationale for each:

**Option 1: Concise & Clear**

* **Description:** 生物學上的特有種，只生長於特定地區的物種。 (Shēngwùxué shàng de tèyǒu zhǒng, zhǐ shēngzhǎng yú tèdìng dìqū de wùzhǒng. – Endemic species in biology, species that only grow in a specific region.)

* **Rationale:** Simple, direct, and easily understood. This is good for tags as they often appear in a list alongside other tags.

**Option 2: Slightly More Informative**

* **Description:** 標記關於特有種的文章，這些物種僅在特定區域或環境中發現，說明其獨特性與生物多樣性。 (Biāojì guānyú tèyǒu zhǒng de wénzhāng, zhèxiē wùzhǒng jǐn zài tèdìng qūyù huò huánjìng zhōng fāxiàn, shuōmíng qí dútè xìng yǔ shēngwù duōyàng xìng. – Tagged articles about endemic species, species only found in specific regions or environments, highlighting their uniqueness and biodiversity.)

* **Rationale:** Provides a little more context, emphasizing the uniqueness and connection to biodiversity.

**Option 3: Targeting Environmental Focus**

* **Description:** 關注本地特有種，包括植物、動物等，及其面對的環境挑戰和保育措施。 (Guānzhù běndì tèyǒu zhǒng, bāokuò zhíwù, dòngwù děng, jíqí miànduì de huánjìng tiǎozhàn hé bǎoyù cuòshī. – Focusing on local endemic species, including plants, animals, etc., and the environmental challenges and conservation efforts they face.)

* **Rationale:** If your website frequently covers conservation and environmental issues, this provides a relevant focus. It is suitable if your blog features issues or focuses on conservation efforts on the endemic species.

**Option 4: More Detailed and Inviting**

* **Description:** 對於自然愛好者，深入探索世間特有種的奧秘。了解哪些生物只屬於我們的土地，它們的獨特性，以及我們如何保護這些珍貴的物種，維護地球的生物多樣性。 (Duìyú zìrán àihǎo zhě, shēnrù tànsuǒ shìjiān tèyǒu zhǒng de àomì. Liǎojiě nǎxiē shēngwù zhǐ shǔyú wǒmen de tǔdì, tāmen de dútè xìng, yǐjí wǒmen rúhé bǎohù zhèxiē zhēnguì de wùzhǒng, wéihù dìqiú de shēngwù duōyàng xìng. – For nature lovers, delve into the mysteries of the world’s endemic species. Learn which creatures belong only to our land, their uniqueness, and how we can protect these precious species and safeguard Earth’s biodiversity.)

* **Rationale:** This aims to engage readers explicitly. The description is longer, but it has a friendly tone and provides a clear idea of what the posts tagged with “特有種” will cover. Best for attracting potential readers.

**How to choose:**

* **Context:** Consider the overall subject matter of your website or blog.
* **Tag Usage:** How many posts do you expect to tag with this? A more detailed description is appropriate if you use this tag frequently.
* **Target Audience:** What level of biological knowledge do your readers have?
* **Space:** The WordPress system may limit how many characters you can put into the description; shorter is often better for tags.

For instance, if your blog focuses on local wildlife conservation, **Option 3 would be the best choice.** If your blog aims for a general audience and a broad range of topics, **Option 2** or **Option 4** would be good starting points. **Option 1** is a great default. Choose the option that best suits your needs! Good luck!
